get_request

Read client request, return Request obj. Currently only GET is supported.

Doomed.

urldecode(s)

Return %-unescaped string of url string.

hex_to_int

Called from above to convert a hex string to integer.

make_query_hash

Split a query string at '&' and return a hash of foo=bar items. The hash keys and values are urldecoded already.

Class HTTP;Message ^

Methods

__init()

Create a new Message object.

headers()

Return an OrderedHash of message headers.
