## The

Syntax: SetEnvIfNoCase attribute regex envar[=value] [...]
Default: none
Context: server config
Override: none
Status: Base
Module: mod_setenvif
Compatibility: Apache 1.3 and above

The `SetEnvIfNoCase` is semantically identical to the `SetEnvIf` directive, and differs only in that the regular expression matching is performed in a case-insensitive manner. For example:

       SetEnvIfNoCase Host Apache\.Org site=apache

This will cause the `site` envariable to be set to "`apache`" if the HTTP request header field `Host:` was included and contained `Apache.Org`, `apache.org`, or any other combination.
