EDITORS NOTE: HTTP/1.1 uses persistent connection causing this delay. Use
"Connection: close" header to disable it.
Just a note to everyone who is using fsockopen and fread / fgets for a HTTP

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

Are you saying the header Connection: Close is ignored?

Any reason why Drupal should not use HTTP/1.1?
