Apache rewrite rule regex

Question

I'm trying to write a rewrite rule to redirect files in my new webhelp system (it's a stand alone website). I have two things I try to take into account - I want to redirect only files that are in the http://www.mydomain.com/webhelp folder. I need to change the .html in the end to .htm... I manage to find each rule by itself by matching the http://www.mydomain.com/webhelp , but when I try the rewrite cond it breaks...

Basically, its http://www.mydomain.com/webhelp/hello.html into http://www.mydomain.com/webhelp/hello.htm without changing http://www.mydomain.com/index.html

Would really appreciate any help. Thanks!

Answer 1

You need to use backreferences. Something like:

RewriteRule   ^www/webhelp/(.*)[.]html([#])(.*)[.]html$ www/webhelp/$1.htm$2$3.htm
RewriteRule   ^www/webhelp/(.*)[.]html$ www/webhelp/$1.htm

Answer 2

If you put the following in a .htaccess file in your webhelp folder, it should achieve what you're looking for:

RewriteEngine on

RewriteBase /webhelp/
RewriteRule ^(.*).html$ $1.htm [R=301,L]
