Why this RewriteRule doesn't work? - .htaccess

I'm developing a web site containing 3 pages (Home, page2, page3) ... in the second page there is a navigation bar, with 4 items (subpage1, subpage2, ...), that I use to replace the content of the page 2 with url variables! In other words, the second item of the navigation bar in page2 points to:
http://localhost/uk/page2/index.php?pg=subpage2
the item 3 point to:
http://localhost/uk/page2/index.php?pg=subpage3
Now I would like to use more friendly urls via .htaccess!
I've written this:
RewriteEngine On
RewriteRule /uk/page2/(.*)/$ /uk/page2/index.php?pg=$1
in the .htaccess placed in the root!
But doesn't work!
Please help!!!

When you're using .htaccess you don't have the leading slash:
RewriteEngine On
RewriteRule ^uk/page2/(.*)/$ /uk/page2/index.php?pg=$1

G'day,
I'd suggest enabling the RewriteLog config option at a high level to check what's actually happening under the covers.
Has AllowOverides been enabled?</obvious> (-:
Seems like you're out of luck using .htaccess
Unbelievably mod_rewrite provides URL manipulations in per-directory context, i.e., within .htaccess files, although these are reached a very long time after the URLs have been translated to filenames. It has to be this way because .htaccess files live in the filesystem, so processing has already reached this stage. In other words: According to the API phases at this time it is too late for any URL manipulations. - Apache mod_rewrite doc.s (emphasis mine)

It may be the trailing slash at the end, so change this:
RewriteEngine On
RewriteRule /uk/page2/(.*)/$ /uk/page2/index.php?pg=$1
to this:
RewriteEngine On
RewriteRule ^(.*)uk/page2(/?)(.*)$ /uk/page2/index.php?pg=$3
Another thing you should check is that you have AllowOverride set to All in your httpd.conf file, instead of None. If it is set to None, you won't be allowed to do anything with .htaccess.

mod_rewrite and dynamic pages

I tried following a tutorial on the internet about mod_rewrite but it wasn't really for me. I created a .htaccess file that has the following code for now:
Options +FollowSymLinks
Options +Indexes
RewriteEngine On
From what I understand this is the basic setup of .htaccess to rewrite urls, followed by the instructions... what and how to change. I tried different exampled but it didn't worked for me. I have a dynamic page with the url localhost/alpha/oferta.php?id=52042156c65d4, where id="..." is the unique id of that offer. I want to change it to localhost/alpha/oferta/id=".."
Can you please show me an example of how can I achieve that? Also if you know any helpful tutorials let me know. Let me know before downrating so I can edit my question. Thanks!
So you want this kind or URL : localhost/alpha/oferta/id=123abc to be redirected to localhost/alpha/oferta.php?id=123abc.
Options +FollowSymLinks
Options +Indexes
RewriteEngine On
RewriteBase /
RewriteRule ^alpha/oferta/id=([A-Za-z0-9]+)$ alpha/oferta.php?id=$1 [L]
Remember a few things :
this won't magically change "old" URLs into "new" ones. You must use rewritten ("new") URLs everywhere. Then your htaccess will change this readable URL into a technical one, which can be used by your code.
this redirection is transparent. If you want the URL to change into the browser bar, use [L,R=301] instead of [L].
this will only accept letters (case insensitive) and numbers for your id.
you can find a good cheat sheet about mod_rewrite here.

Redirect any url containing /foo/

I'm trying to redirect a series of around 400 urls using .htaccess/Apache containing a given /directory/ anywhere in the url to a specific location.
The problem here is that my site is receiving requests for an old site hosted on our servers ip. I've tried manually redirecting the urls but the volume is simply too great.
I've searched but can only find examples for redirecting query strings or files
Thanks in advance.
Ok, if all links have the same directory in there... example store/funstuff/blahblah.php
and funstuff is the directory you are looking for then you could modify your .htaccess file something linke this
Options +FollowSymlinks
Options -Multiviews
RewriteEngine On
RewriteCond %{REQUEST_URI} funstuff
RewriteRule . http://www.gohere.com/
Then if you needed to pass more of the URL info you could do the last line like this:
RewriteRule ^(.*)$ http://www.gohere.com/1$
That should get you started... you may need to tweak it slightly.
What language are you processing the redirects in?
You probably need to use a regular expression that searches for the given /directory/.
If I understand your question correctly and that you are using Apache; RedirectMatch should do what you want.
It accepts a regexp for matching and can then redirect to the place you choose.

.htaccess dynamic to static URL

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.

Stop mod_rewrite returning REQUEST_URI when (.*) is empty

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/

How do I use .htaccess to redirect to a URL containing HTTP_HOST?

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/
