[users@httpd] RedirectMatch wrongly matching single chars of a string?
Hi List,
I've got following problem:
I want to redirect all requests like
site.com/something,
site.com/something/someotherthing,
site.com/something/xyz/someotherthing
to site.com/something.html, no matter if or without trailing slash BUT NOT
if the URL is a .gif, .jpg etc.
So I've got the following RedirectMatch:
RedirectMatch permanent ^/(.[^/(\.gif)(\.jpg)]*)/?
http://www.site.com/$1.html
It works fine for anything after site.com/ NOT containing g, i, f, j, p or .
e.g.:
site.com/xyzxyz -> site.com/xyzxyz.html
site.com/xxxx/yxyx -> site.com/xxxx.html
but: site.com/xxgxx -> site.com/xx.html although I bracketed \.gif etc.
What's wrong? Can anyone make a suggestion?
greets, hb.

Finally, I got it! Thanks Joshua, you brought me on the right way. Here it
is:
RewriteRule ^/$ /start.html [R=permanent,L]
RewriteCond %{REQUEST_URI} !\.(gif|jpg|...etc...)$ [NC]
RewriteRule ^/(.[^/]*)/? /$1.html [R=permanent,L]
Thanks, hb.

Yes it would. Notice the [R=permanent] flag and look it up in the docs.
The other big advantage to mod_rewrite is the RewriteLog, which lets
you figure out exactly what is happening.

I tried your RewriteMatch proposal. It could work with a RewriteCond and a
RewriteRule but this wouldnt change the URL in the user's address bar and
that's what I want.

You tried which proposal? The RewriteRule one can be easily fixed by adding
RewriteCond %{REQUEST_URI} !\.html$

Thanks for the reply. Yes, I was wrong with thinking [^gif] would match only
the whole string. Got that in the meantime. I just tested your proposal but
it does not work =/ It redirects to /file.gif.html, /file.gif.html.html etc.
etc. in an infinite loop. ergo: it matches and redirects.

You need to look again at a regex tutorial. Stuff inside [] is a
character class, not an arbitrary regex. That means it will match any
one of the set of characters included in the class. You need
something more like
RedirectMatch permanent ^/(.*(?!\.(gif|jpg)))/?$ http://www.example.com/$1.html
I haven't tested that, and the negative-lookahead assertion will
certainly only work in httpd 2.x.
Another way to do this that doesn't require as much regex magic is
RewriteEngine On
RewriteCond %{REQUEST_URI} !(gif|jpg)$
RewriteRule ^/(.*)/?$ http://www.example.com/$1[R=permanent]
