htaccess equivalent to PHP's $_SERVER['SERVER_NAME']?

I have a need to dynamically input the current domain name, into an htaccess file. This would be trivial in PHP but I can't figure out how to do it in "Apache Speak" and my Apache-fu is weak.

For the record, I've tried this:

SetEnvIfNoCase Referer %{SERVER_NAME} internal

and this:

SetEnvIfNoCase Referer %{HTTP_HOST} internal

but frankly I'm not sure if I'm even on the right track at all. The end result I'm after would look something like:

SetEnvIfNoCase Referer currentdomain.com internal

Try asking yourself, is there a different approach to your problem?

If there isn't a simple answer, it's most likely that there is a different way to approach the situation.

For example, if you could insert it dynamically once and write the .htaccess with php, you could possibly save yourself trouble and maybe even efficiency in your code.

You can do this:

SetEnvIfNoCase Referer www\.whateveryourdomain\.com internal

The syntax for SetEnvIfNoCase is like this:

SetEnvIfNoCase attribute regex [!]env-variable[=value] [[!]env-variable[=value]] ...

From Apache Docs attribute can have:

  • An HTTP request header field (see RFC2616 for more information about these); for example: Host, User-Agent, Referer, and Accept-Language. A regular expression may be used to specify a set of request headers.
  • One of the following aspects of the request:
    • Remote_Host - the hostname (if available) of the client making the request
    • Remote_Addr - the IP address of the client making the request
    • Server_Addr - the IP address of the server on which the request was received (only with versions later than 2.0.43)
    • Request_Method - the name of the method being used (GET, POST, et cetera)
    • Request_Protocol - the name and version of the protocol with which the request was made (e.g., "HTTP/0.9", "HTTP/1.1", etc.)
    • Request_URI - the resource requested on the HTTP request line -- generally the portion of the URL following the scheme and host portion without the query string. See the RewriteCond directive of mod_rewrite for extra information on how to match your query string.
  • The name of an environment variable in the list of those associated with the request. This allows SetEnvIf directives to test against the result of prior matches. Only those environment variables defined by earlier SetEnvIf[NoCase] directives are available for testing in this manner. 'Earlier' means that they were defined at a broader scope (such as server-wide) or previously in the current directive's scope. Environment variables will be considered only if there was no match among request characteristics and a regular expression was not used for the attribute.

The same applies for SetEnvIfNoCase.

There isn't one. If you're running 2.4 then you can use SetEnvIfExpr, but 2.2 or earlier require some work with mod_rewrite.
