Bug #14827: POST [file upload] timeout in browsers

From: michael@antipersonnel.org Operating system: windows 2000 PHP version: 4.1.0 PHP Bug Type: HTTP related Bug description: POST [file upload] timeout in browsers i am attempting to have users upload files from their computer to my web server. i seem to be experiencing a timeout in both IE and NN. i have changed the server and php.ini settings accordingly, but timeouts still occur. i have gone through many lists and forums looking for an answer, and while i notice people posting they can upload [quite] large files, no one details the network environment [ie., intra/internet], browser, web server, client machine, etc. i am sure someone out there is experiencing timeouts in both IE and NN when attempting to upload large files. i can upload files fine, until the filesize is greater than what i can upload within the timeout. IE times out at about 5 minutes, and NN varies around there. so far, the largest file i have been able to upload was about 10MB or so, on a t1. i have tried the ReceiveTimeout registry entry for IE, but it does NOT work in IE6. i have a prefs.js entry for NN that might work, but have to wait until tonight to test it out. now, i know it is the browser that is timing out [at home at least]. is there a way to keep sending pertinent info to the browser during a copy() function, in order to keep the connection alive, and not have the browser timeout? or, is there another way to do a file upload via the broswer, that won't time out? i cannot tell is this is a php bug, a browser bug, or just plain old operator headspace. thanking you in advance. sincerely, michael defrees here are my current settings: server: win2k adv server IIS 5 php 4.1.0 webserver settings: connection timeout = 1800 php.ini settings: max_execution_time = 1800 memory_limit = 50M post_max_size = 50M file_uploads = On upload_tmp_dir = c:\php\upload_temp upload_max_filesize = 50M the page is here: http://www.antipersonnel.org/ordnance/musicbox/upload.php please do not be malicious, the error handling was removed in order to debug the timeout. files uploaded will be located here: http://www.antipersonnel.org/index.php?directory=upload here is the code: <? $sizelimit = "no"; $sizebytes = "200000"; $dl = "http://www.antipersonnel.org/ordnance/musicbox/upload"; $absolute_path = "d:/inetpub/wwwroot/antipersonnel.org/upload"; $websiteurl = "http://www.antipersonnel.org"; $websitename = "antipersonnel.org"; switch($action) { default: echo" <head> <title>upload</title> </head> <body> <a href=$PHP_SELF?action=upload>Upload File</a> <a href=$websiteurl>Return to $websitename</a> </body> "; break; case "upload": echo" <head> <title>upload</title> </head> <body> <form method=POST enctype=multipart/form-data action=$PHP_SELF?action=doupload> <p>File to upload:<br> <input type=file name=file size=30> <p><input value=submit name=submit type=submit> </form> </body> "; break; //File Upload case "doupload": $dir = "dir"; if ($file != "") { if (file_exists("$absolute_path/$file_name")) { die("File already exists"); } if (($sizelimit == "yes") && ($file_size > $sizebytes)) { die("File is to big.
