| 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. |
