The Apache::Gateway module implements a gateway using LWP with assorted optional features. From the HTTP/1.1 draft, a gateway is:

[a] server which acts as an intermediary for some other server.
Unlike a proxy, a gateway receives requests as if it were the origin
server for the requested resource; the requesting client may not be
aware that it is communicating with a gateway.

Features:

  • Standard gateway features implemented using LWP

  • Automatic failover with mirrored instances

  • Multiplexing

  • Pattern-dependent gatewaying

  • FTP directory gatewaying

  • Timestamp correction

Available from CPAN. See the module manpage for more information.
