Another lovely mod_rewrite problem...

Using mod_rewrite with an external map file...

[Gadnium]

Hello again everyone.

I have a little problem regarding the www.

Here's what I have so far THAT WORKS(Partially)

###
# Map File
###
domain1.com/clients/72504
domain2.com/clients/72505
domain3.com/clients/72506
...

###
# httpd.conf
###

UseCanonicalName Off
RewriteEngine On

RewriteMap lowercase int:tolower
RewriteMap vhost txt:/www/conf/vhosts.map

RewriteCond ${lowercase:%{SERVER_NAME}} ^(.+)$
RewriteCond ${vhost:%1} ^(/.*)$
RewriteRule ^/(.*)$ %1/$1 [L]

This setup works fine when the URL is example1.com. However, it does NOT work with www.example1.com.

I know I could simply add another entry with the www. in my map file like:

domain1.com/clients/72504
www.domain1.com/clients/72504

However, this is unnecessary if I can have apache remove the www automatically.

How can I remove the www portion of the URL in order to match my map file?

Thanx in advance,

Gadnium

I haven't used this mapping technique before, but here's a guess:

RewriteCond ${lowercase:%{SERVER_NAME}} [b]^(www\.)?[/b](.+)$
RewriteCond ${vhost[b]:%2}[/b] ^(/.*)$
RewriteRule ^/(.*)$ %1/$1 [L]

Thanks but I've already tried that.

This would still require the double entry in the map file because it is matching the entire string with or without the www.

I need to remove the www if present.

Nope,

There are two subpatterns there, and only %2 is passed to your vhost: map. "www.", if present, is assigned to %1, and promptly dropped.

My Fault..

Your solution works:
RewriteCond ${lowercase:%{SERVER_NAME}} ^(www\.)?(.+)$
RewriteCond ${vhost:%2} ^(/.*)$
RewriteRule ^/(.*)$ %1/$1 [L]

As I did not know the %1 was dropped:
RewriteCond ${lowercase:%{SERVER_NAME}} ^(www\.)?(.+)$
RewriteCond ${vhost:%2} ^(/.*)$
RewriteRule ^/(.*)$ %2/$1 [L]

Thank You.
