Topic: mod_rewrite with certain parameters

[Mark1979]

Hi Guys,

I hope someone can help with this problem, it's driving me mad!

I have a folder on my website with 000's of banners which people are linking to. I want to redirect these to new banners of the same size.

I have looked at Mod_Rewrite and ReWrite rules but cant seem to get it right. The code should...

-Look for '468x60' in the filename
-If it does, redirect to another file.

E.g.

www.mysite.com/banners/banner468x60.gif
www.mysite.com/banners/another468x60.gif

would redirect to

www.anothersite.com/newbanners/banner468x60.gif

but

www.mysite.com/banners/banner120x60.gif would not be redirected.

Hope that makes sense.

I think a custom error handler for that folder could be a solution. Maybe a server side script which handles 404 errors and than redirects to the new folder.

e.g

Hey James,

Thanks for the quick response, that does sound like a good option.

Hmm, that doesnt seem to work either.

It seems that HTTP_REFERER doesn't work for 404's - or I can't get them to work anyway. the Http referer just shows my_404_handler.php as the referring page.

For the ErrorDocument route ... is FileInfo one of the AllowOverrides for the folder or folder/s above it in the tree? The only reason I cannot think of that it would not work as this is a pretty standard way to serve up custom error documents.

You are using the wrong variable Try $_SERVER['REQUEST_URI']


---- edit ---


There are two different variables that I find very useful in Caching and similar.

$_SERVER['REQUEST_URI'] and $_SERVER['REQUEST_URL']

URI provides the entire request path (/directory/file.ext?query=string)
URL provides the request path, without the query string (/directory/file.ext)
It also differs from __FILE__ in that it's not the file name. So, if you go to /directory/anotherfile.ext and get silently redirected to file.ext, these variables are anotherfile.ext, while __FILE__ is still file.ext.
