Keepalive: better fastcgi testing.
With previous fastcgi keepalive patches minimal number of bytes that should
be fed to input filter (pipe->length) wasn't always set correctly. Try
harder to catch this.

Keepalive balancer module for nginx. This module implements cache for backend connections. As of now, it may be used with memcached upstreams. Note: don't even try it with http backends. It won't work. Note: it's for nginx 0.7.* and won't work with nginx 0.6.*. Configuration directives: keepalive <num> [single] Scope: upstream Switches on keepalive module for the upstream in question. Parameters: - <num> Maximum number of connections to cache. If there isn't enough room to cache new connections - last recently used connections will be kicked off the cache. - single Treat everything as single host. With this flag connections to different backends are treated as equal. Sample configuration: upstream memd { server 127.0.0.1:11211; server 10.0.0.2:11211; keepalive 10; } This module was tested to work with standard round-robin balancing, but it's believed to be compatible with more sophisticated balancers. The only requirement is to activate them *before* this module, e.g.: upstream memd { server 127.0.0.1:11211; server 10.0.0.2:11211; ip_hash; keepalive 10; } To compile nginx with keepalive module, use "--add-module <path>" option to nginx configure.
