Hello All, I've got a strange issue with our deployment of HAProxy 1.6 where a user will make a request to a page, and as each page element comes in, the time taken shown on each file downloaded in the IE developer tools increases by a factor of 3, until finally the user is prompted for credentials, but the page load never continues. I should mention that this is an ASP.NET web application running with Integrated Windows Authentication on IIS 8. I know, I know, IE + IIS + IWA = terrible, but it's hard for the enterprise to not use these platforms internally, especially the IWA single sign on part.
So a request looks like this in the developer tools: mainpage.aspx - HTTP 200 - 130.04KB - 421ms css file - HTTP 200 - 1.51KB - 296ms css file - HTTP 200 - 14.93KB - 0.96s css file - HTTP 200 - 13.99KB - 2.73s css file - HTTP 200 - 29.92KB - 8.14s css file - HTTP 200 - 23.44KB - 24.36s webresource.axd - Pending - Pending - Pending (this is where the user is prompted for credentials) And on that last file is where it then prompts for credentials, which never works because I believe that HAProxy has hit the timeout and closed the connection, and breaking IWA. I should mention that our HAProxy server works great 99.9% of the time, and we do a lot of L7 load balancing on different URLs, and host headers, and we handle a good amount of traffic that returns page elements in ms, and it also handles Integrated Windows Auth fine - most of the time. It's just these occasional things that have me at a loss. Any suggestions from the mailing list?
