htaccess if statement

Question

I have the following line in my .htaccess file to select which version of PHP to use:

AddType x-httpd-php53 .php

This works great

Answer 1

Another alternative you can do is to change httpd.conf in the test environment to use ".htaccess-test" instead of ".htaccess".

This is simply done by modifying httpd.conf and adding the following line outside of any block:

AccessFileName .htaccess-test

NOTE: You can add AccessFileName inside a <VirtualHost> block if you want to apply it to a specific VirtualHost.

What this means is that the test environment will use .htaccess-test while the production environment will use .htaccess. Hence, you get the freedom of configuring each environment separately.

Then create a file named .htaccess-test adjacent to .htaccess. Modify .htaccess-test with your test configuration, then finally restart Apache Web server in the test environment server.

With Apache 2.4, it is easy with <If>/<Else> directives (on %{HTTP_HOST}?).

<If "%{HTTP_HOST} == 'foo'">
    # configuration for foo
</If>
<Else>
    # default configuration
</Else>

For Apache 2.2 and earlier, I would add a parameter to the startup command line of Apache (-D option) in one of the two environments then test if it is present or not via <IfDefine>.

To do this on Windows, with Apache started as a service, modify key registry HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Apache2.<VERSION>\ImagePath
by appending -DFOO. Then, you can write:

<IfDefine FOO>
    # configuration for foo
</IfDefine>
<IfDefine !FOO>
    # default configuration
</IfDefine>
