If you can figure out this you are indeed among the elite of troubleshooting. We have a remote site connected to our main site over a Full T-1 connection. We also have a backup DSL connection from this remote site to the main site connected using DMVPN (Dynamic Multipoint VPN) in case the T-1 link goes down. Now here is the weird issue. Users at the remote site "connected via the T-1" while trying to use a certain "web based http" (the application in stored at the main site on a server) application experience applicaiton lockup and extreme slowness, now when they try to use "https" the issue goes away and they experience no applicaiaton lockups of slowness. On the other hand when testing if we take the T-1 down and use the much slower backup DMVPN connection both http and https work just fine! Granted the applicaiton is a little slow because they are going through the internet and it is encrypted, but the application does not lockup using http or https. Thanks in advance for any suggestions.
I have this problem too.
