2 * HA-Proxy : High Availability-enabled HTTP/TCP proxy

10 * Please refer to RFC2068 or RFC2616 for informations about HTTP protocol, and
11 * RFC2965 for informations about cookies usage. More generally, the IETF HTTP
12 * Working Group's web site should be consulted for protocol related changes :
13 *
14 * http://ftp.ics.uci.edu/pub/ietf/http/
15 *
16 * Pending bugs (may be not fixed because never reproduced) :
17 * - solaris only : sometimes, an HTTP proxy with only a dispatch address causes
18 * the proxy to terminate (no core) if the client breaks the connection during
19 * the response. Seen on 1.1.8pre4, but never reproduced. May not be related to
20 * the snprintf() bug since requests were simple (GET / HTTP/1.0), but may be
21 * related to missing setsid() (fixed in 1.1.15)
22 * - a proxy with an invalid config will prevent the startup even if disabled.
23 *
24 * ChangeLog has moved to the CHANGELOG file.
