I am trying to rewrite all the old oscommerce links to a new website. But I am having trouble with part of the URL I need to rewrite.
The link looks like this:
http://www.domain.com/product_info.php?cPath=3_72&products_id=129&osCsid=6j3iabkldjcmgi3s1344lk1285
This rewrite works for the above link:
RewriteCond %{REQUEST_URI} ^/product_info\.php$
RewriteCond %{QUERY_STRING} ^cPath=3_72&products_id=129&osCsid=([A-Za-z0-9-_]+)$
RewriteRule ^(.*)$ http://www.domain.com/apple/air.html? [R=301,L]
But will not work for:
http://www.domain.com/product_info.php?cPath=3_72&products_id=129
My problem is that I want the rewrite to work no matter if the &osCsid=6j3iabkldjcmgi3s1344lk1285 part is included or not.
I think you can achieve this by not specifying the closing delimiter ($)
Give this a try:
RewriteCond %{REQUEST_URI} ^/product_info\.php$
RewriteCond %{QUERY_STRING} ^cPath=3_72&products_id=129
RewriteRule ^(.*)$ http://www.domain.com/apple/air.html? [R=301,L]
By not putting the $ at the end of the regex string you are basically saying: match any string that starts with ..., no matter what comes after
Hope this helps :)
This should do the job just fine:
RewriteCond %{QUERY_STRING} ^cPath=3_72&products_id=129
RewriteRule ^product_info\.php$ http://www.domain.com/apple/air.html? [R=301,L]
There is no need for separate condition RewriteCond %{REQUEST_URI} ^/product_info\.php$ -- this part can be (actually, SHOULD BE, for better performance) moved to RewriteRule.
This is enough ^cPath=3_72&products_id=129 -- it tells "When query strings STARTS with ...". No need to include optional/non-important parameters osCsid=([A-Za-z0-9-_]+).
This rule is to be placed in .htaccess file in website root folder. If placed elsewhere some small tweaking may be required.

I am trying to do a redirect to another site. The following rule works perfectly for all the other rules within my .htacces but the following rule does not seem to work and i can'r figure out why, after lots of try and error.
RewriteCond %{HTTP_HOST} ^www.oldexample.com$
RewriteRule ^folder3/page.php?value=(.*)$ http://newexample.com/folder1/page.php?value=$1 [L,R=301,NC]
I tried the following which redirected but without the value within (.*) added
RewriteCond %{HTTP_HOST} ^www.oldexample.com$
RewriteRule ^folder3/page.php?(.*)$ http://newexample.com/folder1/page.php?$1 [L,R=301,NC]
Could this be an issue with the = symbbol? I tried escaping it and escaping the . also but to no avail
You can't match against the query string (everything after the ?) in a rewrite rule, you need to use a RewriteCond and match against the %{QUERY_STRING}. However, it looks like you're just trying to pass the query string along, unchanged. So you don't need to mess with any of it:
RewriteCond %{HTTP_HOST} ^www.oldexample.com$
RewriteRule ^folder3/page.php$ http://newexample.com/folder1/page.php [L,R=301,NC]
The query string will get appended automatically. You need to make sure this rule is above any routing rules as it needs to take place before any internal rewrites.
I'm trying to work on doing some rewrite but it's not working. Here is my code:
RewriteCond %{REQUEST_URI} !^(static/|server/|internal.php).*$
RewriteRule ^(.*)$ /internal.php?request=$1 [L]
I'm trying to redirect everything to /internal.php?request=blablabla, except the internal.php itself, and things in two folders called static and server, since these two folders have images and so on.
For example,
/hello/world => /internal.php?request=hello/world/
/static/a/b/c/a.jpg => /static/a/b/c/a.jpg not changed
But the code is not working, the RewriteCond seems not able to restrict rewrite of internal.php, and the two folders. Now what's happening is everything is going to rewrite to internal.php, and internal.php would be rewrite to internal.php again. And finally give me a 500 after infinite loops. Which I don't want any rewrite happen. What's wrong?
You are missing a leading / in the request URI expression, also you should escape the dot in internal.php so that it actually matches a dot instead of every char:
RewriteCond %{REQUEST_URI} !^/(static/|server/|internal\.php).*$
RewriteRule ^(.*)$ /internal.php?request=$1 [L]
Note that this will also rewrite /static and /server where the trailing slash is omitted, if you want to avoid that you could for example add another condition:
RewriteCond %{REQUEST_URI} !^/(static|server)$
RewriteCond %{REQUEST_URI} !^/(static/|server/|internal\.php).*$
Tough it should be possible to put this in a single expression, however I'm not that experienced with regular expressions, so I'm pretty sure that this not the most elegant way:
RewriteCond %{REQUEST_URI} !^/(((static|server)(/.*)?)|(internal\.php.*))$
I know this sounds like so many other questions here, but I can't seem to find the answer.
Say you are on:
www.domain.com/folderA/folder2/folder3/
I want that to redirect to:
www.domain.com/folderB/folder2/folder3/
So the whole structure stays the same.. it just redirects.
Now so far I have:
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/folderA [NC]
RewriteRule ^(.*)$ /folderB/$1 [R=301,L]
But when I use that, it'll just do
www.domain.com/folderB/folderA/folder2/folder3/
What am I doing wrong? How do I get rid of that folderA?
The pattern ^(.*)$ includes also the prefix folderA. You must specify folderA explicitly in the pattern and capture only the latter part in the RewriteRule. Then you can drop the RewriteCond
RewriteEngine on
RewriteRule ^/?folderA/(.*)$ /folderB/$1 [R,L]
Never test with 301 enabled, see this answer Tips for debugging .htaccess rewrite rules for details.
I currently have this .htaccess rule the works fine:
RewriteRule ^instructor/([A-Za-z0-9-]+)$ instructor.php?username=$1 [NC,L]
However, when I attempt to add a period into the mix a lot of the rules on the site break so I am assuming the character isn't escaped correctly:
RewriteRule ^instructor/([A-Za-z0-9-\.]+)$ instructor.php?username=$1 [NC,L]
Anyone point me in the right direction please?
Update
It appears to be something to do with the directory structure.
Another selection of rules that apply to this site are the following:
## Registration
RewriteRule ^instructor/register/?$ instructor-form/index.php [L]
RewriteRule ^instructor/register/stage([1-5]+)$ instructor-form/stage$1.php [L]
These work fine (the directory here is instructor-form/
However, there is also a directory called instructor/ which these rules point to:
RewriteRule ^instructor/dashboard/?$ instructor/index.php [L]
RewriteRule ^instructor/account-details/?$ instructor/account-details.php [L]
RewriteRule ^instructor/change-password/?$ instructor/change-password.php [L]
These are the rules that are affected when adding the . into the first rule. The rules are all in order and work fine without the . in the [A-Za-z0-9-] char block. When added the physical instructor/ folder seems inaccessible.
You wrote so much text in your question but forgot to mention important details: what is actually broken? Because I do not have clear answer for that I will be speculating here based on the information you have provided so far.
RewriteRule ^instructor/([A-Za-z0-9-\.]+)$ instructor.php?username=$1 [NC,L]
The problem with this rule is that it will also rewrite already rewritten php files: instructor/index.php, instructor/account-details.php, instructor/change-password.php etc.
I think you are relaying on [L] flag too much .. or do not really know how mod_rewrite and [L] flag work. And that is why you are having this issue -- your rule with a dot in pattern rewrites already rewritten URLs.
Useful link: RewriteRule Last [L] flag not working?
You need to add some condition (global rule or condition specific to this rule only) to prevent rewriting already rewritten URLs or existing files.
1. Global rule -- place it somewhere on the top before other rules. Keep in mind that this may not work as intended depending on your website structure and rewrite logic (e.g. when you need to actually rewrite requests to already existing files or folders):
# do not do anything for already existing files
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .+ - [L]
2. Condition specific to that rule only:
a) do not rewrite if requested URI is physical file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^instructor/([A-Za-z0-9-\.]+)$ instructor.php?username=$1 [NC,L]
OR
b) do not rewrite .php files
RewriteCond %{REQUEST_URI} !.+\.php$
RewriteRule ^instructor/([A-Za-z0-9-\.]+)$ instructor.php?username=$1 [NC,L]
It is many topics here about subdomains but no one can help me...
I use htacces to set subdomain to folder
So if we put http://en.example.com/something
I use something like this..
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^(.*)$ http://example.com/%1/$1 [NC]
This works fine but adress in bar is changed to http://example.com/en/something but I want keep http://en.example.com/something
so I tried this
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^([^.]+)\.example\.com(.*) /$1/$2
or just
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^(.*)$ %1/$1 [NC]
but this doesn't work. Any solution or ideas ?
One solution is use language there (http://example.com/en/something) where I rewrite it but after If I work on subdirectories I get something like http://example.com/subdirectory/en/something - terrible.
Maybe I like http://example.com/en/subdirectory/something bud how proceed this...
And also on some private servers first one case send me to "maybe" default domain, so it is not working for me. (maybe this is some server condition or settings)
I know this is a month late, but maybe this will still be useful for somebody. A few things here:
Regarding your first RewriteRule:
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^(.*)$ http://example.com/%1/$1 [NC]
As it seems you already discovered, rewriting to another URL will also redirect the user's browser to that new URL, even if it's at your own domain. To keep it hidden, you have to rewrite to a file path on the server (like you do with your next two rules).
Regarding your second RewriteRule:
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^([^.]+)\.example\.com(.*) /$1/$2
The problem there is that you can't match the domain name in the RewriteRule, only the URL path. If your URL is www.example.com/something/somethingelse, the string you're trying to match is just something/somethingelse. In other words, it excludes www.example.com/, so this RewriteRule pattern you have will never match the domain name because the pattern isn't even being tested against that part of the URL, but you included the domain name in the pattern, causing the match to fail.
Regarding your third RewriteRule:
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$
RewriteRule ^(.*)$ %1/$1 [NC]
This looks like it should work, so I can't say for sure why it isn't without knowing more about how your files are organized on the server and so forth. Let's say you have all of the website's files in /home/somebody/public_html/. In order for the RewriteRule to work as it is right now, you would need to have an en subdirectory in public_html. So, if somebody went to en.example.com/something, the RewriteRule would cause Apache to serve the file at /home/somebody/public_html/en/something. My guess why it's not working for you is that you might have the subdomain pointing somewhere other than public_html (assuming you actually had the website files organized like in my example). Remember that what you're rewriting to (/$1/$2 in this case) is a file path on the server, not a URL to your website.
I hope that helps! You may have already solved this by now, but even if you have, I'm hoping other people will still find this useful.
