Interpreting ISA 407 Error
Hi,
I'm troubleshooting a piece of e-learning that seems to be problematic only when it is launched within our client's network due to its proxy server configuration. The application itself is Flash-based which calls various asp pages and we put in an error handling
script based on the HTTP status of these asp pages when they're loaded.
Attached below is the log that we got from Fiddler (I have changed the domain name). I have minimal networking knowledge but I'm hoping to get some understanding as in:
1) Why does the proxy server sometimes allow these asp pages to load (returning 200 OK) but sometimes it doesn't (returning 407 Proxy Authentication Required)
2) It seems that the 407 event is always followed by a success event (200), and for some reason Flash always thinks it's ok and never picks up the 407 issue. Why is it the case?
3) If I needed to speak to the network engineer, are there specific settings that I should mention to them to rectify this issue?
Any help would be much appreciated! Thank you.
