<title>Expires HF Body Parser</title>
<para>
The parser parses body of Expires header field. The body is very
simple, it consists of number only. so the parser only removes any
leading tabs and spaces and converts the number from string to
integer. That's it.
</para>
<para>
The parser can be found in file <filename>parse_expires.c</filename>
under <filename>parser</filename> subdirectory. Main function is
<function>parse_expires</function>. The function is not called
automatically when an Expires header field was found. It is up to you
to call the function if you need the body to be parsed.
</para>
<para>
The function creates a new instance of
<structname>exp_body_t</structname> structure and calls the parser. If
everything went OK, pointer to the newly created structure will be
saved in <structfield>parsed</structfield> field of the
<structname>hdr_field</structname> structure representing the parsed
header field.
</para>
