NAME ^

Apache::AxKit::Plugin::AddXSLParams::Request - Provides a way to pass info from the Apache::Request to XSLT params

SYNOPSIS ^

  # in httpd.conf or .htaccess
  AxAddPlugin Apache::AxKit::Plugin::AddXSLParams::Request
  PerlSetVar AxAddXSLParamGroups "Request-Common HTTPHeaders"

DESCRIPTION ^

A strong contender for longest package name of the year, Apache::AxKit::Plugin::AddXSLParams::Request offers a way to make information about the current client request (cookies, headers, uri info) available as params within XSLT stylesheets.

CONFIGURATION ^

This plugin is added to the request cycle by using the AxAddPlugin directive.

  AxAddPlugin Apache::AxKit::Plugin::AddXSLParams::Request

This package introduces the AxAddXSLParamGroups config option, which takes a space-seperated list of 'tags' (see PARAM GROUPS below) that are used to add groups of related information to the param list. Note that this is not a first-class config directive and must be added via PerlSetVar:

  PerlSetVar AxAddXSLParamGroups "List Of Groups"

PARAM GROUPS ^

In an effort to provide an easy-to-setup way to make external data->XSL param mapping work while letting folks choose only the types of info that they are interested in, sets of related information are grouped with an identifying 'tag'. This tag is passed in via the AxAddXSLParamGroups config directive which is used to determine which groups of info will be passed along as params. For example:

  AxAddXSLParamGroups "Request-Common HTTPHeaders VerboseURI"

will configure this package to include the sets of data identified by the Request-Common, HTTPHeaders, and VerboseURI tags.

The param groups that this package implements are detailed below.

Request-Common ^

A minimal set of common parameters extracted from the request instance.

Param Prefix: request.*

Implemented Fields:

Examples:

  <xsl:param name="request.method"/>
  <xsl:param name="request.uri"/>
  <xsl:param name="request.path_info"/>
  <xsl:param name="request.filename"/>

HTTPHeaders ^

Provides access to HTTP headers sent by the client.

Param Prefix: request.headers.*

Implemented Fields:

The headers sent during a request vary somewhat from client to client; this group will contain all the headers returned by the request object's headers_in() method using the convention: request.headers.fieldname where fieldname is name of the given HTTP header field, forced to lower case.

If any HTTP Cookies are found in the headers, they will be parsed and values available as XSLT params using the naming convention: request.cookies.yourcookiename. See the Cookies group below for an alternative way to access cookies.

More common headers include:

Examples:

  <xsl:param name="request.headers.accept-language"/>
  <xsl:param name="request.headers.host"/>
  <xsl:param name="request.headers.user-agent"/>
  <xsl:param name="request.headers.referer"/>

Cookies ^

Provides an alternative way to access the HTTP Cookies header for those folks that want to get at the cookie data but don't want to pull in all of the other HTTP headers.

Param Prefix: request.cookies.*

Implemented Fields:

Cookie values are made available as params using the convention: request.cookies.yourcookiename

Examples:

  <xsl:param name="request.cookies.oreo"/>
  <xsl:param name="request.cookies.chocolate-chip"/>
  <xsl:param name="request.cookies.fortune"/>

VerboseURI ^

Offers fine-grained access to the URI requested (via Apache::URI's parse_uri() method.

Param Prefix: request.uri.*

Implemented Fields:

Examples:

  <xsl:param name="request.uri.path"/>
  <xsl:param name="request.uri.scheme"/>
  <xsl:param name="request.uri.port"/>
