Difficult rewrite rule

[riccardo83]

hi guys,
at the moment i redirect this link:

http://www.example.com/topic,14063,.html
to this:
http://www.example.com/viewtopic.php?t=14063

by using

RewriteRule ^topic,([0-9]+),.html?$ viewtopic.php?t=$1 [L]

But how is it possible to rewrite

http://www.example.com/topic,17183,-fanvid.html
to
http://www.example.com/viewtopic.php?t=17183?

its like removing something what you dont know, -fanvid could be any other syntax...

I'm not sure why you said this is difficult, but I'd suggest:

RewriteRule ^topic,([0-9]+),[b]-fanvid[/b]\.html$ viewtopic.php?t=$1 [L]

For more information, see the documents cited in our forum charter [webmasterworld.com] and the tutorials in the Apache forum section of the WebmasterWorld library [webmasterworld.com].

RewriteRule ^topic,([0-9]+),([-A-Za-z0-9%-]+)\.html?$ viewtopic.php?t=$1 [L]

One problem at a time, please...

You say that -fanvid "could be anything" -- Can you be more specific?
Is it always preceded by a comma? does it always start with "-"? Is it always there, or is it optional?

You need to fully define all possible variations in order to write a regular-expressions pattern to match.

It is possible to strip off extra characters from a URL by (bracketing) all characters after the last one that you will know will always be there and then not reusing those characters in the new URL.
