Apache Module mod_version

Available Languages:  en  | + fr  | + ja  | + ko

Description:Version dependent configuration
Status:Extension
Module Identifier:version_module
Source File:mod_version.c
+

Summary

+ +

This module is designed for the use in test suites and large + networks which have to deal with different httpd versions and + different configurations. It provides a new container -- <IfVersion>, which + allows a flexible version checking including numeric comparisons and + regular expressions.

+ +

Examples

<IfVersion 2.4.2>
+    # current httpd version is exactly 2.4.2
+</IfVersion>
+
+<IfVersion >= 2.5>
+    # use really new features :-)
+</IfVersion>
+
+ +

See below for further possibilities.

<IfVersion> Directive

+ + + + + + + +
Description:contains version dependent configuration
Syntax:<IfVersion [[!]operator] version> ... +</IfVersion>
Context:server config, virtual host, directory, .htaccess
Override:All
Status:Extension
Module:mod_version
+

The <IfVersion> section encloses + configuration directives which are executed only if the + httpd version + matches the desired criteria. For normal (numeric) comparisons the + version argument has the format + major[.minor[.patch]], e.g. + 2.1.0 or 2.2. minor and + patch are optional. If these numbers are omitted, they are + assumed to be zero. The following numerical operators are + possible:

+ + + + + + + + + + + + +
operatordescription
= or ==httpd version is equal
>httpd version is greater than
>=httpd version is greater or equal
<httpd version is less than
<=httpd version is less or equal
+ +

Example

<IfVersion >= 2.3>
+    # this happens only in versions greater or
+    # equal 2.3.0.
+</IfVersion>
+
+ +

Besides the numerical comparison it is possible to match a + regular expression + against the httpd version. There are two ways to write it:

+ + + + + + +
operatordescription
= or ==version has the form + /regex/
~version has the form + regex
+ +

Example

<IfVersion = /^2.4.[01234]$/>
+    # e.g. workaround for buggy versions
+</IfVersion>
+
+ +

In order to reverse the meaning, all operators can be preceded by an + exclamation mark (!):

+ + 
<IfVersion !~ ^2.4.[01234]$>
+    # not for those versions
+</IfVersion>
+ + +

If the operator is omitted, it is assumed to be + =.
