[Libevent-users] libevent-1.4.0 beta released

[william at opensource4you.com]

First of all happy new year to all ;-).


Second, sorry for the delay, but free time is more and more difficult to
find.

I propose here a patch for "evhttp_dispatch_callback" that allow him to
treat wild char in registered uri.
(patch is based on libevent-1.4.1-beta)


in attach you will find a test: "libevent-test.c" that will implement such
uri.
In the sample, I register "/test*" to the function "callback_http_index".
That means that this function will be triggered when the browser will
request the uri /test/12345/read (for example).

This give much more flexibility.

Thanks
