| 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. |

| 2027 | * If maxconn is set and not maxsslconn, maxsslconn is computed from |
| 2028 | * the remaining amount of memory between memmax and the cleartext |
| 2029 | * connections. If neither are set, then it is considered that all |
| 2030 | * connections are SSL-capable, and maxconn is computed based on this, |
| 2031 | * then maxsslconn accordingly. We need to know if SSL is used on the |

| 2033 | * we need twice the value for maxsslconn, but we only count the |
