.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`APR::Request\*(C'\fR module provides the base methods
for interfacing with libapreq2's module \s-1API\s0.  It also provides
a few utility functions and constants.
.PP
This manpage documents version 2.08
of the APR::Request, APR::Request::Custom,
APR::Request::Cookie::Table, and
APR::Request::Param::Table packages.

.Ve
.PP
Creates a new APR::Request::Custom object.  The \f(CW$query_string\fR
and \f(CW$cookie_headers\fR are immediately parsed into the \f(CW\*(C`args\*(C'\fR and
\&\f(CW\*(C`jar\*(C'\fR tables.  The \f(CW$parser\fR is an APR::Request::Parser object
which is invoked when fetching \f(CW\*(C`body\*(C'\fR entries from the \f(CW$brigade\fR.
The \f(CW$read_limit\fR represents the maximum number of bytes this handle
may feed into the parser.

With no arguments, this method returns a tied APR::Request::Cookie::Table
object (or undef if the \*(L"Cookie\*(R" header is absent) in scalar context, or

With the \f(CW$key\fR argument, in scalar context this method fetches the first
matching cookie.  In list context it returns all matching cookies.
The returned cookies are the values as they appeared in the incoming
Cookie header.
.PP
\&\fIjar()\fR will throw an APR::Request::Error object whenever \fIjar_status()\fR 
is non-zero and the return value is potentially invalid (eg
