(Apache 2.2.10, PHP 5.2.14) The browser and / or OS may be obeying the settings about the number of simultaneous connections per host. http://support.microsoft.com/kb/183110 / http://www.ietf.org/rfc/rfc2616.txt 8.1.4 Practical Considerations ... " Clients that use persistent connections SHOULD limit the number of simultaneous connections that they maintain to a given server. A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy. A proxy SHOULD use up to 2*N connections to another server or proxy, where N is the number of simultaneously active users. These guidelines are intended to improve HTTP response times and avoid congestion." Also, (from googling) http://forums.serverbeach.com/showthread.php?6192-Max-Concurrent-Connections-Per-Host, mod_throttle and/or mod_bandwidth may be capable of restricting the number and/or speed of connections. -- Richard Quadling Twitter : EE : Zend : PHPDoc @RQuadling : e-e.com/M_248814.html : bit.ly/9O8vFY : bit.ly/lFnVea
