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
    =.
