Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

So on an Apache bundled with PHP as a module, I want to prepend a file if referer is x. This is what I have so far:

<IfModule mod_setenvif.c>
    SetEnvIf Referer http://backoffice\.mywebsite\.wan27/ BackOfficeListens

<IfDefine BackOfficeListens>
    <IfModule mod_php5.c>
        php_value auto_prepend_file /path/to/php/file

I should also say to the BackOffice Server is on my local, so backoffice.mywebsite.wan27 is a local host, but apparently the PHP on the target server recognizes it.

You can't use IfDefine to test the values of an environment variables. Take a look at the core Apache documentation, specifically:

The parameter-name argument is a define as given on the httpd command line via -Dparameter- , at the time the server was started.

I don't know the best way of handling this. One option would be to always prepend the file:

SetEnvIf Referer http://backoffice\.mywebsite\.wan27/ BackOfficeListens
php_value auto_prepend_file /path/to/php/file

And then inside the PHP file, check for your environment variable and perform your intended logic only if the variable is set:


if (isset($_ENV['BackOfficeListens'])) {
    echo("BackOfficeListens is set.");
