apache - How Can I Have A Conditional .htaccess Block?

Question

This is an Apache question you've probably come across before. I want to have one source package that I can deploy to my workstation, my staging server, and my production server, but for it to load different .htaccess settings based on what the URL was.

Note that I was using a kludge with an IfModule call, but that won't work with our new production server because it shares all the same modules as my staging server.

Note I need to bundle SetEnv with these rewrites. Currently if you use RewriteCond, it only ties to the following RewriteRule, but not the SetEnv underneath.

Answer 1

Instead of using SetEnv, use the environment variable setting capabilities of RewriteRule itself:

RewriteCond %{HTTP_HOST} =foo.com
RewriteRule ^ - [E=VARNAME:foo]

RewriteCond %{HTTP_HOST} =bar.com
RewriteRule ^ - [E=VARNAME:bar]

Although I prefer doing this sort of thing by passing flags to the httpd process at startup and looking for them using IfDefine blocks.

<IfDefine FOO>
SetEnv VARNAME foo
</IfDefine>

<IfDefine BAR>
SetEnv VARNAME bar
</IfDefine>
