Hi, Louis, You'll probably want to start by asking the people who administer the central weblogin servers at your institution. Since you're at the University of Michigan, I happen to know that you can reach your central weblogin server administrators at cos...@umich.edu. Include as much information in your report as possible. For example: - Does this happen with only some cosign-protected web servers, or all? If only some, list which ones. - Does this happen with all users, or only some? - Does this happen with all web browsers and operating systems, or only some? - Does it make a different as to whether a user has previously authenticated to the central weblogin servers, or is unauthenticated and is asked to authenticate when they access the cosign protected web server? - If the slowness is when accessing a cosign-protected web server that you run, which cosign filter is it running, and which version, under what version of what web server? Include any other relevant configuration about the web server, including any log entries, suspicious system statistics, etc. And, most importantly... - What requests is your web browser issuing, at what times, and what responses is it getting back from each web server involved, at what times? This will show you where the slowness is and allow you and the central weblogin server administrators to start looking in the right place. The Firefox add-on "Live HTTP Headers" can gather this information for you. Safari's Web Inspector might also be able to do it. And there should be a way to achieve a similar result in Microsoft Internet Explorer, too. I hope this helps. -- Mark Montague m...@catseye.org ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Cosign-discuss mailing list Cosign-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cosign-discuss
