[users@httpd] Having problem while requesting for pages while downloading something from http server.

[paritosh mahana]

Hi,
I have set up apache http server version 2.0.53. I am having problem when I try to access some data via php while downloading some file. The download thing is done by calling a php script. And in the middle of downloading when I try to access some other php from the server it gives connection time out error and the connection that  I had established for file download closes by itself without any exception. The download thing is done by calling the readfile() function.

Another thing is that when I try to download something from my server it works fine via the php page.(No other requests for any other page)But when I want to start another download then it just waits for the first download to finish. So why are they not sharing resources, like my bandwidth, and why the 2nd wait for the 1st to finish. Is there any configuration setting for this that I have messed up. Or do I have to add something in my php files.

current server config:
Apache2.0.53
php4.3.10

Thanks.
