Simple regex problem - please help.

[jeddiki]

Hi ,

My simple redirect is working EXCEPT if there is a period in the string.

This is what I have:

RewriteCond %{HTTP_HOST} ^([^.]+).example.net [NC]
RewriteCond %{HTTP_HOST} !^www.example.net [NC]

RewriteRule ^.*$ http://example.net/disp_page.php?a=%1 [NC,QSA,L]

So this works fine with :

potatoes.exampl e.net

that goes to example.net/disp_page.php?a =potatoes

and the page displays

BUT if I have

recipes.potatoe s.example.net

then it doesn't work

It should go to : example.net/disp_page.php?a =recipes.potato es

Which would work fine.

Does any one know how I should adjust my code above so that it takes everything up to the ".example.n et"?

Thanks.

RewriteCond %{HTTP_HOST} ^(.+)\.example\.net [NC]

Backslash your periods. They're special characters in regexes -- the reason that your code actually happens to work is because the period selects anything. This would have even matched www4exampleanet .
This new regex just selects everything before the string ".example.n et"
