For example I have a page http://www.f1u.org/en/its-interesting/166-cricri.
How to write rule: if that page exists - open it.
If it returns 404, then redirect to http://www.f1u.org/its-interesting/166-cricri
use this line in .htaccess file
ErrorDocument 404$ http://www.f1u.org/its-interesting/166-cricri
It sounds like you want the apache server to look ahead to see if the current URL exists, if not, redirect them. I think you might be able to use mod_rewrite to accomplish this.
My first stab at it would be something like:
RewriteEngine On
RewriteCond %{IS_SUBREQ} false
RewriteCond %{REQUEST_URI} !-U
RewriteRule /en(/.*) $1 [R,L]
I'll note that I haven't tried it so the syntax and effects could be slightly off, and you'd need to be careful that you don't put yourself into an infinite loop, or wind up with too many subrequests (as that could impact the performance of your server). But hopefully it'll give you a starting point to play with. Alternatively mod-rewrite could (depending on server permissions) let you invoke scripts to determine rewrites as well, which could be an option as well.

We're seeing some really weird URLs in our logs and I've been told to start redirecting them.
I know of a couple of better ways to go about fixing this, but the boss wants it done this way. I apologize in advance.
We're seeing stuff like the following in our logs:
http://www.example.com/foo/bar/bla&ob=&ppg=&rpp=100&ob=&rpp=&ppg=&rpp=30&ppg=&ppg=1&rpp=10&rpp=50&ob=&ob=&ob=&rpp=40&ob=&rpp=5&rpp=30&rpp=&rpp=20&order_by=&results_per_pge=75
I've been told to 'toss some mod_rewrite rules in the .htaccess file' to take this and strip out all the ob, rpp, and ppg variables.
Now, I've found ways to strip everything out. And that wouldn't be too bad if I could leave the /foo/bar/bla in there. But I can't seem to do that. Basically, any help would be appreciated.
Try:
# strip out any params that's ob=, rpp= or ppg=
RewriteRule ^/?(.*)&ob=([^&]*)&(.*)$ /$1&$3 [L]
RewriteRule ^/?(.*)&rpp=([^&]*)&(.*)$ /$1&$3 [L]
RewriteRule ^/?(.*)&ppg=([^&]*)&(.*)$ /$1&$3 [L]
# if everything's gone, finally redirect and fix query string
RewriteCond %{REQUEST_URI} !&(ob|rpp|ppg)
RewriteRule ^/?(.*?)&(.*) /$1?$2 [L,R=301]
The problem here is that your URL:
http://www.example.com/foo/bar/bla&ob=&ppg=&rpp=100&ob=&rpp=&ppg=&rpp=30&ppg=&ppg=1&rpp=10&rpp=50&ob=&ob=&ob=&rpp=40&ob=&rpp=5&rpp=30&rpp=&rpp=20&order_by=&results_per_pge=75
has A LOT of ob=, rpp=, and ppg= in the URI. More than 10. That means you'll get a 500 internal server error if you use these rules against that URL. By default, apache has the internal recursion limit set to 10, that means if it needs to loop more than 10 times (and it will for the above URL), it'll bail and return a 500. You need to set that higher:
LimitInternalRecursion 30
or some other sane number. Unfortunately, you can't use that directive in an htaccess file, you'll need to go into server or vhost config and set it.
I'm trying to make my dynamic URL's into static looking URL's.
This is a typical URL that I now have:
http://www.somedomain.com/design/index.php?p=about
I would like it to be: http://www.somedomain.com/about
So far, I've gotten it to look like this: http://www.somedomain.com/design/about.html
This is the Rewriterule I'm using: RewriteRule ^([a-z]+).html$ index.php?p=$1 [L]
How would I modify it so it would look like this: http://www.somedomain.com/about?
Thanks for any/all help!!!
Very much appreciated!
Using rewrite rules to give 'static' URI is NEVER a good idea.
A few other ideas you can use:
Make the 'about' page a directory (folder) with a file called index.php or index.html in it. This way the URL shows http://example.com/about/ and the information you wish can still be displayed as needed.
Use the POST method instead of GET methods. This will display as http://example.com/about.php (Note: there is no ? or other parameters behind that.)
Utilize both methods to give a 'seamless' URI on page transitions.
Rick, you're on the right track. You need to read the Apache rewrite documentation. For your docroot/.htaccess start it with:
RewriteEngine On
RewriteBase /
Then generalised version of your rule:
Rewrite Rule ^(\w+)$ index.php?p=$1 [L]
This will rewrite any requests which are for a word string to index.php. You need to be aware that the rewrite engine rescans the .htaccess file if a match has occured so you need to make sure that you don't create a loop. In this case the replacement string has a "." in it and the pattern doesn't, so this won't occur, but for more complex cases you may need to 'guard' the rules with one or more RewriteCond statements. Again, read the Apache documentation.
i'm using an htaccess script trying to remove the .php testing the .htaccess on a testing server it runs fine, but on the live server that is a different host it trys rewriting the file based on the absolute path and the rewrite fails
here is the htaccess:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
this is taking a url like this www.example.com/services
and trying to point it to /n/c/example.com/public/service.php
I know the {REQUEST_FILENAME} is suppose to be pulling the full local system path, but i don't understand why it's not finding the file. i know very little about htaccess and mod_rewriting so i'm not really sure what I should try to make it base everything off of just the url path, or if there is a better solution. I'm really open to suggestions.
Any help would be greatly appreciated.
Thanks
Use RewriteRule .* %{REQUEST_URI}.php [L]
It is hard to tell why your rule did not worked for you by having so little info about your Apache setup and any other rewrite rules that you may have.
Quite possible that the [L] flag did the trick for you -- you may have other rewrite rules that were rewriting this URL further, producing incorrect result in the end. I don't think that %{REQUEST_URI} did such a big job on its own, unless you have some symbolic links / aliases or even some transparent proxy in use which could make a difference.
Keep in mind, that the rules you have shown in your question cannot generate this sort of URL to be visible in browser's address bar (example.com//service.php/) -- it has to be a redirect (3xx code) involved .. which suggests that you have other rules somewhere.
Most likely it is a combination of your Apache specific settings & combined rewrite rules logic (where the L flag can make a big difference depending on those other rules).
The only way to give more precise answer will be enabling rewrite debugging and analyzing how rewrite was executed and what was involved.
Have you enabled mod_rewrite on the other server? AddModule mod_rewrite, I think.
Also - more likely - have you enabled .htaccess? You would need to have
AllowOverride All
or
AllowOverride FileInfo
for that.
These directives will need to go in the apache config files (usually /etc/httpd/conf/httpd.conf or one of the files in /etc/httpd/conf.d), and you will need to restart apache to get them to take effect.
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^mocks/site/(.*)$ http://thelivewebsite.com/$1 [R=301,L]
That is my htaccess file's contents.
The htaccess file is in the root directory of the hosting account and I just want to redirect the directory mocks/site/ to the new domain (with or without any extra directories).
eg: if someone goes to http://mywebsite.com/mocks/site then it needs to redirect to http://thelivewebsite.com. If they go to http://mywebsite.com/mocks/site/another/directory then it needs to redirect to http://thelivewebsite.com/another/directory. I hope that makes sense.
So the problem I have is that the htaccess code above seems to work pretty well when there is something after mocks/site/ however when there isn't something after that then the $1 in the redirect seems to reference the whole REQUEST_URI (eg: mocks/site/ rather than nothing - as there is nothing after it).
I don't know how to stop this. I thought about using a RewriteCond, but I'm not sure what to use there. I can't find anything that helps me to determine if there is anything after mocks/site/ or not.
Any help will be much appreciated.
Thank you.
That's very strange behaviour -- never seen anything like that. Therefore I think it could be something else (another rule somewhere -- on old or even new site). I recommend enabling rewrite debugging (RewriteLogLevel 9) and check the rewrite log (that's if you can edit Apache's config file / virtual host definition).
In any case, try this combination:
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^mocks/site/$ http://thelivewebsite.com/ [R=301,L]
RewriteRule ^mocks/site/(.+)$ http://thelivewebsite.com/$1 [R=301,L]
It will do matching/redirecting in 2 steps: first rule is for exact directory match (so no $1 involved at all) and 2nd will work if there is at least 1 character after the /mocks/site/.
Alternatively (Apache docs even recommending this one) use Redirect directive (no need for mod_rewrite at all for such simple redirects):
Redirect 301 /mocks/site/ http://thelivewebsite.com/
Problem
I need to redirect some short convenience URLs to longer actual URLs. The site in question uses a set of subdomains to identify a set of development or live versions.
I would like the URL to which certain requests are redirected to include the HTTP_HOST such that I don't have to create a custom .htaccess file for each host.
Host-specific Example (snipped from .htaccess file)
Redirect /terms http://support.dev01.example.com/articles/terms/
This example works fine for the development version running at dev01.example.com. If I use the same line in the main .htaccess file for the development version running under dev02.example.com I'd end up being redirected to the wrong place.
Ideal rule (not sure of the correct syntax)
Redirect /terms http://support.{HTTP_HOST}/articles/terms/
This rule does not work and merely serves as an example of what I'd like to achieve. I could then use the exact same rule under many different hosts and get the correct result.
Answers?
Can this be done with mod_alias or does it require the more complex mod_rewrite?
How can this be achieved using mod_alias or mod_rewrite? I'd prefer a mod_alias solution if possible.
Clarifications
I'm not staying on the same server. I'd like:
http://example.com/terms/ -> http://support.example.com/articles/terms/
https://secure.example.com/terms/ -> http://support.example.com/articles/terms/
http://dev.example.com/terms/ -> http://support.dev.example.com/articles/terms/
https://secure.dev.example.com/terms/ -> http://support.dev.example.com/articles/terms/
I'd like to be able to use the same rule in the .htaccess file on both example.com and dev.example.com. In this situation I'd need to be able to refer to the HTTP_HOST as a variable rather than specifying it literally in the URL to which requests are redirected.
I'll investigate the HTTP_HOST parameter as suggested but was hoping for a working example.
It's strange that nobody has done the actual working answer (lol):
RewriteCond %{HTTP_HOST} support\.(([^\.]+))\.example\.com
RewriteRule ^/terms http://support.%1/article/terms [NC,QSA,R]
To help you doing the job faster, my favorite tool to check for regexp:
http://www.quanetic.com/Regex (don't forget to choose ereg(POSIX) instead of preg(PCRE)!)
You use this tool when you want to check the URL and see if they're valid or not.
I think you'll want to capture the HTTP_HOST value and then use that in the rewrite rule:
RewriteCond %{HTTP_HOST} (.*)
RewriteRule ^/terms http://support.%1/article/terms [NC,R=302]
If I understand your question right, you want a 301 redirect (tell browser to go to other URL).
If my solution is not the correct one for you, try this tool: http://www.htaccessredirect.net/index.php and figure out what works for you.
//301 Redirect Entire Directory
RedirectMatch 301 /terms(.*) /articles/terms/$1
//Change default directory page
DirectoryIndex
According to this cheatsheet ( http://www.addedbytes.com/download/mod_rewrite-cheat-sheet-v2/png/ ) this should work
RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain2.com/$1
Note that i don't have a way to test this so this should be taken as a pointer in the right direction as opposed to an explicit answer.
If you are staying on the same server then putting this in your .htaccess will work regardless of the server:
RedirectMatch 301 ^/terms$ /articles/terms/
Produces:
http://example.com/terms -> http://example.com/articles/terms
or:
http://test.example.com/terms -> http://test.example.com/articles/terms
Obviously you'll need to adjust the REGEX matching and the like to make sure it copes with what you are going to throw at it. Same goes for the 301, you might want a 302 if you don't want browsers to cache the redirect.
If you want:
http://example.com/terms -> http://server02.example.com/articles/terms
Then you'll need to use the HTTP_HOST parameter.
You don't need to include this information. Just provide a URI relative to the root.
Redirect temp /terms /articles/terms/
This is explained in the mod_alias documentation:
The new URL should be an absolute URL beginning with a scheme and hostname, but a URL-path beginning with a slash may also be used, in which case the scheme and hostname of the current server will be added.
It sounds like what you really need is just an alias?
Alias /terms /www/public/articles/terms/
