Subject Re: UDP support in mod_perl2/apache
Date Thu, 01 Nov 2007 13:16:08 GMT
I put out a patchset a few months ago to support UDP in trunk and 2.2.x
branches of httpd (for a mod_dns protocol module that we're  currently
in the process of releasing to the public).  The patchset only works for
the unix flavor of APR and the prefork MPM at the moment (I'm sure if it
gets adopted we can work out the other MPMs and APR flavors)

You can grab the patchset for trunk at

The same patchset can be used for 2.2.x branch pretty much as is with
the single addition of backporting the apr_socket_sendto function from
trunk (it's broken in the APR that ships with 2.2.x)

If you have any issues applying it/using it/integrating with mod_per
(though I don't think the mod_perl API should need any tweaking to
utilize this), I'd be happy to work with you (or whomever else).

With ApacheCon & the hackathon coming up soon, this would be a great
time to ping dev@httpd for possible inclusion in trunk...
