Weird fsockopen behavior

Hi I'm using $fp=fsockopen($URL,80, &$errno, &$errstr,10); set_socket_blocking($fp,false); to get the HTML from a remote site and monitor how long it took me to DL the HTML. The next lines are like this : if ($fp) { $SendGetStart = getmicrotime(); fwrite($fp,"GET / HTTP/1.1\r\n"); fwrite($fp,"Accept: */*\r\n"); fwrite($fp,"Accept-Language: en-us\r\n"); fwrite($fp,"Proxy-Connection: Keep-Alive\r\n"); fwrite($fp,"User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; COM+ 1.0.2204)\r\n"); fwrite($fp,"Host:$Host\r\n\r\n"); .......... While(!feof($fp)) {............... The weird thing is that it seems the EOF comes in great delay. When I print the HTML I get from the remote site, the while loop continues for about 10-15 seconds after the last </HTML> tag arrived. This is for any site I check so it's not something specific to the web server I'm testing. Anyone has any idea why? Thanks berber
