htaccess Issue

[kickstart]

Hi

 

I had an htaccess issue which I hope someone can help me with:-

 

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ GrabImage.php?username=$1

 

The idea is that any request to a gif in that directory should be passed to GrabImage.php.

 

However while if I invoke GrabImage.php directly it works fine, if I specify an image name instead  I get a 404 error. If I change "GrabImage.php" to "/Index.php" in the script it redirects it successfully to the root index script (happens to be a phpbb forum) for that domain.

 

If I specify a gif in that directory with a name which is not just alphabetics (so the RewriteRule is not met) then the image is served perfectly. If I rename the image and try again with the new name (which the RewriteRule meets) then I get a 404 error.

 

I suspect I have missed something simple here, and it does work fine on my wamp setup on my desktop machine, just not when I upload it.

 

Thanks in advance.

 

All the best

In that case, try -

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ GrabImage.php?username=$1

Hi

 

Cheers, but no difference.

 

What is "Rewritebase /" attempting to do? Is is trying to specify that any requests are not redirected by appache to another directory?

 

All the best

Well I assumed GrabImage.php is in your root directory. You sure you have the path right?

Hi

 

No, GrabImage is in the directory with the images.

 

If I put a slash in front of GrabImage.php (or some other script name I put there such as Index.php) it will pick it up from the root.

So like:

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ GrabImage/GrabImage.php?username=$1

 

Did I understand you correctly?

Hi

 

Had more of a play.

 

The directory is like:-

 

/publichtml/sitedirectory/subdirectory1/subdirectory2/

 

subdirectory2 contains the GrabImage.php script and the .htaccess file. Also an Index.php that is a clone of GrabImage.php.

 

If I try the following it doesn't work. Just get a 404 error

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ Index.php?username=$1

 

If I try the following it pics up the Index.php from that sites directory (ie /publichtml/sitedirectory/Index.php)

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ /Index.php?username=$1

 

If I try the following it does actually work.

Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} ^.*\.gif$
RewriteRule ([a-zA-Z]+)\.gif$ /subdirectory1/subdirectory2/Index.php?username=$1

 

"RewriteBase /" appears to have no effect.

 

My understanding was that the rewrite rule was relative to the local directory unless specified otherwise but that doesn't appear to be the case.

 

All the best
