This module provides the ability to specify character set translation or recoding.
Status: Experimental
Source File:
mod_charset_lite.c
Module Identifier:
charset_lite_module
This is an experimental module and should
be used with care. Experiment with your
mod_charset_lite
configuration to ensure that it
performs the desired function.
mod_charset_lite
allows the administrator to
specify the source character set of objects as well as the
character set they should be translated into before sending to
the client. mod_charset_lite
does not translate
the data itself but instead tells Apache what translation to
perform. mod_charset_lite
is applicable to EBCDIC
and ASCII host environments. In an EBCDIC environment, Apache
normally translates text content from the code page of the
Apache process locale to ISO-8859-1.
mod_charset_lite
can be used to specify that a
different translation is to be performed. In an ASCII
environment, Apache normally performs no translation, so
mod_charset_lite
is needed in order for any
translation to take place.
This module will only work if APACHE_XLATE
is
defined at compile time.
This module provides a small subset of configuration
mechanisms implemented by Russian Apache and its associated
mod_charset
.
The character set name parameters of CharsetSourceEnc and CharsetDefault must be acceptable to the translation mechanism used by APR on the system where mod_charset_lite is deployed. These character set names are not standardized and are usually not the same as the corresponding values used in http headers. Currently, APR can only use iconv(3), so you can easily test your character set names using the iconv(1) program, as follows:
iconv -f charsetsourceenc-value -t charsetdefault-value
If the translation rules don't make sense for the content, translation can fail in various ways, including:
Syntax: CharsetSourceEnc
charset
Default: None
Context: directory, virtual
host
Override:
FileInfo
Status: Experimental
Module: mod_charset_lite
The CharsetSourceEnc
directive specifies the
source charset of files in the associated container.
The value of the charset argument must be accepted as a valid character set name by the character set support in APR. Generally, this means that it must be supported by iconv.
Example:<Directory "/export/home/trawick/apacheinst/htdocs/convert"> CharsetSourceEnc UTF-16BE CharsetDefault ISO8859-1 </Directory>The character set names in this example work with the iconv translation support in Solaris 8.
Syntax: CharsetDefault
charset
Default: None
Context: directory, virtual
host
Override:
FileInfo
Status: Experimental
Module: mod_charset_lite
The CharsetDefault
directive specifies the
charset that content in the associated container should be
translated to.
The value of the charset argument must be accepted as a valid character set name by the character set support in APR. Generally, this means that it must be supported by iconv.
Example:<Directory "/export/home/trawick/apacheinst/htdocs/convert"> CharsetSourceEnc UTF-16BE CharsetDefault ISO8859-1 </Directory>
Syntax: CharsetOptions
option [option] ...
Default: DebugLevel=0
NoImplicitAdd
Context: directory, virtual
host
Override:
FileInfo
Status: Experimental
Module: mod_charset_lite
The CharsetOptions
directive configures certain
behaviors of mod_charset_lite
. Option can
be one of
mod_charset_lite
. By default, no messages are
generated. This is equivalent to DebugLevel=0.
With higher numbers, more debug messages are generated, and
server performance will be degraded. The actual meanings of
the numeric values are described with the definitions of the
DBGLVL_ constants near the beginning of
mod_charset_lite.c
.mod_charset_lite
should implicitly insert its
filter when the configuration specifies that the character
set of content should be translated. If the filter chain is
explicitly configured using the AddOutputFilter directive,
NoImplicitAdd should be specified so that
mod_charset_lite
doesn't add its filter.
