the way to accomplish this is via the NE (no escape) paramater.

    RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]

should in fact read

    RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,NE,L]

this will force mod_rewrite to leave all query string values as they are, without doing any encoding / escaping.

as easy as that :)

What does it do *internally*? Does it use unsafe code? 
And why is it so fast (compared to the `+` operator)?

So my co-worker felt it necessary to go onto my development box and do some code changes, then submit his work to subversion.  I never set the commit message editor, and all of a sudden, one day I forgot to add the `-m` handle and apparently he set the default editor to `emacs`.

Being that I don&#39;t know the first thing about `emacs` and prefer `vim` myself, how do I go about changing the default editor for SVN commands to `vim` after it&#39;s already been set?  I deleted the `.subversion` directory under the home directory, and it still prompts me.

We have some very basic mod_rewrite rules:

    RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]

mod_rewrite seems to do its job, and if the user is accessing:

`something.swf?param=value`, it is redirected correctly to `http://www.newdomain.com/something.swf?param=value`

the problem is in this situation:

    www.olddomain.com/something.swf?param=URL_ENCODED_VALUE

what ends up happening is mod_rewrite takes it upon it self to re-urlencode the query string param

so what the user ends up with is:

    www.olddomain.com/something.swf?param=URL_ENCODED_VALUE

REDIRECTED TO

    www.newdomain.com/something.swf?param=URL_ENCODED_VALUE_OF_URL_ENCODED_VALUE

so we end up with a double-urlencoded value. boourns!

While I do understand we could make a `\?(.*)` ... `?$1` rule for this, I am thinking there must be a way to tell mod_rewrite NOT to urlencode the query string params... we would like to avoid using 2 rules since valid paths are:

    something.swf (no query string)

and

    something.swf?someparams...

so yea, ideally... just tell mod_rewrite: please, no urlencoding of query string params... just direct passthru to the new URL via `R=302`.

I recently tried to set a test server up with Apache. The site must run under domain `www.mytest.com`. I always get a `403 Forbidden` error. I am on Ubuntu 10.10 server edition. The doc root is under dir `/var/www`. The following are my settings:

I have no `.htaccess` file in my doc root. The permissions are set correctly (readable by www-data).

If I type in the IP address from my desktop, the site shows up correctly. I changed the hosts file on my desktop to point `www.mytest.com` to the server&#39;s IP. When I use it, I get `403`. Since many functions of this site are sitename-sensitive, I have to be able to access the site by the domain name.

Another funky thing is, even if all log files are created properly, they have no information regarding this error.

I am stuck. Can anybody help?

Apache VirtualHost 403 Forbidden

I am having an issue when I have a php application that is returning an internal server error (500) however nothing is showing up in the error log.

Now I know there are error with what I am trying to run, I know I have missing some files and what not but something should show in the apache error log (otherwise how are I supposed to know exactly what I am missing).

I created a test script is errors it in under the same vhost configuration and those error show up fine so everything seems configured right as far as php/apache.  Are there certain php errors that does show up in the error log (php is configure to display any type of notice, warning, , error, fatal error, etc...)?

This is running on ubunut 10.04 with the standard apache and php from the ubuntu repo with apt-get.

I have following command in my .htaccess

        RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
        RewriteRule ^(.*?)-([a-z]+) %2/$1.$2 [L]
        RewriteRule ^(.*?)-([0-9]+)([a-z]) %2/$1$3.$2 [L]

%2 is not working in second and later lines.
Can I define any variable for %2 and use it in all RewriteRule commands?
Following command works   

         RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
         RewriteRule ^(.*?)-([a-z]+) %2/$1.$2 [L]
         RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
         RewriteRule ^(.*?)-([0-9]+)([a-z]) %2/$1$3.$2 [L]
But I want use %2 for multiple rule line without duplicating condition.


Multiple RewriteRules for single RewriteCond in .htaccess

Currently I am using the hosting with **lightspeed** server. Hosting says `mod_rewrite` is enabled but I can&#39;t get my script working there. Whenever I try to access the URL, it returns **404 - not found** page.

I put the same codes at another server which is running with Apache. It&#39;s working over there. So I guess, it&#39;s the `.htaccess` and `mod_rewrite` issue.

But Hosting support is still insisting with me that their mod_rewrite is on, so I would like to know how can I check whether it&#39;s actually enabled or not.

I tried to check with `phpinfo()`, but no luck, I can&#39;t find `mod_rewrite` there, is it because they are using `lightspeed`?

Is there any way to check? Please help me out. Thank you.

**FYI:** my `.htaccess` code is

    Options -Indexes
    
    &lt;IfModule mod_rewrite.c&gt;
    DirectoryIndex index.php
    RewriteEngine on
    
    RewriteCond $1 !^(index\.php|assets|robots\.txt|favicon\.ico)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]
    &lt;/IfModule&gt;

I tried like this also


    DirectoryIndex index.php
    RewriteEngine on
    
    RewriteCond $1 !^(index\.php|assets|robots\.txt|favicon\.ico)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

But same result.

How to check whether mod_rewrite is enable on server?

I was wondering if it is possible to check if `mod_rewrite` is enabled on **Apache** AND **IIS** in **`PHP`**.

**ModRewrite** for IIS exists. Check it [`here`][1].

So, I&#39;m looking for a PHP script that checks for `mod_rewrite` on **Apache** and **IIS.**

Does anyone know such script or can write one?

Especially for Microsoft **IIS**.

Thanks!

How to check if mod_rewrite is enabled in php?

Many posters have problems debugging their RewriteRule and RewriteCond statements within their **`.htaccess`** files.  Most of these are using a shared hosting service and therefore don&#39;t have access to the root server configuration. They cannot avoid using `.htaccess` files for rewriting and _cannot_ enable a RewriteLogLevel&quot; as many respondents suggest.  Also there are many `.htaccess`-specific pitfalls and constraints are aren&#39;t covered well.  Setting up a local test LAMP stack involves too much of a learning curve for most.   

So my Q here is how would we recommend that they ***debug*** their rules _themselves_.  I provide a few suggestions below.  Other suggestions would be appreciated.

 1. **Understand that the mod_rewrite engine cycles through `.htaccess` files**. The engine runs this loop:

        do
          execute server and vhost rewrites (in the Apache Virtual Host Config)
          find the lowest &quot;Per Dir&quot; .htaccess file on the file path with rewrites enabled
          if found(.htaccess)
             execute .htaccess rewrites (in the user&#39;s directory)
        while rewrite occurred

    So your rules will get executed repeatedly and if you change the URI path then it may end up executing other `.htaccess`files if they exist. So make sure that you terminate this loop, if necessary by adding extra `RewriteCond` to stop rules firing.  Also delete any lower level `.htaccess` rewrite rulesets unless explicitly intent to use multi-level rulesets.  

 2. **Make sure that the syntax of each Regexp is correct** by testing against a set of test patterns to make sure that is a valid syntax and does what you intend with a fully range of test URIs.  See [answer below][1] for more details.

 3. **Build up your rules incrementally in a test directory.**  You can make use of the &quot;execute the deepest `.htaccess` file on the path feature&quot; to set up a separate test directory (tree) and debug rulesets here without screwing up your main rules and stopping your site working.  You have to add them one at a time because this is the only way to localise failures to individual rules.

 4. **Use a dummy script stub to dump out server and environment variables**. (See **Listing 2**)If your app uses, say, `blog/index.php` then you can copy this into `test/blog/index.php` and use it to test out your blog rules in the `test` subdirectory.  You can also use environment variables to make sure that the rewrite engine in interpreting substitution strings correctly, e.g.

        RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

    and look for these **REDIRECT_\*** variables in the phpinfo dump.  BTW, I used this one and discovered on my site that I had to use `%{ENV:DOCUMENT_ROOT_REAL}` instead.  In the case of redirector looping  **REDIRECT_REDIRECT_\*** variables list the previous pass. Etc.. 

 5. **Make sure that you don&#39;t get bitten by your browser caching incorrect 301 redirects**.  See [answer below][2].  My thanks to [Ulrich Palha][3] for this.

 6. The rewrite engine seems sensitive to cascaded rules within an `.htaccess` context, (that is where a `RewriteRule` results in a substitution and this falls though to further rules), as I found bugs with internal sub-requests [(1)][4], and incorrect **PATH_INFO** processing which can often be prevents by use of the \[NS\], \[L\] and \[PT\] flags.

Any more comment or suggestions?

Tips for debugging .htaccess rewrite rules

I have a `RewriteRule` in a `.htaccess` file that isn&#39;t doing anything. How do I troubleshoot this?

* How can I verify if the `.htaccess` file is even being read and obeyed by Apache? Can I write an echo &quot;it is working&quot; message, if I do write it, where would that line be echoed out?
* If the `.htaccess` file isn&#39;t being used, how can I make Apache use it?
* If the `.htaccess` is being used but my `RewriteRule` still isn&#39;t having an effect, what more can I do to debug?
