Hints and tips on apache

These are some helpful hints on various topics.


Adding www to domain name

If you want you users and search bots to be redirected from http://domain.com/some-page.html to http://www.domain.com/some-page.html for any page some-page.html add the following code to you .htaccess file.

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.domain\.com$
RewriteRule .* http://www.domain.com%{REQUEST_URI} [L,R=301]

Erorr "400 Bad request" when using mod_rewrite

Sometimes when you use mod_rewrite you get "400 Bad request" error, when accessing directory  without  trailing slash. For example http://domain.com/forum returns "400 Bad request" when forum is directory while http://domain.com/forum/ has normal response. To fix this issue use this fragment in your .htaccess file:

RewriteCond    %{REQUEST_FILENAME}  -d
RewriteCond    %{REQUEST_URI}  (.*)
RewriteRule    (.+)[^/]           %1/  [R=301,L]

Installing Apache as Windows service

If you have not installed Apache webserver  on Windows via installer but from source or tarball then it will not be installed as service. To fix this press Start->Run and type in:
apache -i -n "Apache"
