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 --
, which allows a flexible version checking including numeric comparisons and regular expressions.
# current httpd version is exactly 2.1.0
# use really new features :-)
See below for further possibilities.

模块 | mod_version |
section encloses configuration directives which are executed only if thehttpd
version matches the desired criteria. For normal (numeric) comparisons theversionargument has the formatmajor[.minor[.patch]]
, e.g.2.1.0
或2.2
.minor和patchare optional. If these numbers are omitted, they are assumed to be zero. The following numericaloperators are possible:
operator | description |
---|---|
= 或== |
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 |
# this happens only in versions greater or
# equal 2.1.0.
Besides the numerical comparison it is possible to match a regular expression against the httpd version. There are two ways to write it:
operator | description |
---|---|
= 或== |
versionhas the form/regex/ |
~ |
versionhas the formregex |
# e.g. workaround for buggy versions
In order to reverse the meaning, all operators can be preceded by an exclamation mark (!
):
# not for those versions
If theoperatoris omitted, it is assumed to be=
.
