Hi! I'm running a web application on our local server running Apache version 2.0.50-7mdk and Squid Version: 2.5.STABLE6-2.2.101mdk on Mandrakelinux 10.1. When i connect to the server from a client computer and click a button which runs a php-script and returns a .png file to a window, i receive this error: ERROR The requested URL could not be retrieved While trying to retrieve the URL: http://192.168.0.3/ern/ijb/report/print_reportgd.php? The following error was encountered: Zero Sized Reply Squid did not receive any data for this request. Your cache administrator is root. Generated Tue, 08 Mar 2005 08:35:47 GMT by server02 (squid/2.5.STABLE6) If i right-click on the window and refresh a few times, i could get the .png image. I found some information here: http://www.squid-cache.org/Doc/FAQ/FAQ-11.html but it doesnt seem to solve the problem. I would also like to note that when i used a Nokia 9500 to access the server and perform the same thing it had no problem displaying the png file. The browser i tested on the client computers include Konqueror, Firefox and IE6. I hope my explanation is clear enough. If not, please let me know. Thank you.
