Ashraf,

>From the comments at the PHP fsockopen page:
===
EDITORS NOTE: HTTP/1.1 uses persistent connection causing this delay. Use
"Connection: close" header to disable it.

and

Just a note to everyone who is using fsockopen and fread / fgets for a HTTP
connection.

Unless you specify "Connection: Close" in your headers you will need to wait
for the socket to time out before feof($streamPointer) to return true.

This has wasted 2 days of my time, grr!

The first example in the page, before the comments, also does the close for
this reason.

This is detailed in the RFC too
http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1

Are you saying the header Connection: Close is ignored?

Any reason why Drupal should not use HTTP/1.1?
