Why would an ASP.NET site become veeeeeery slow after the network connection dropped?

I have an ASP.NET 3.5 site published in IIS 7.5 on Windows Server 2008 R2 64 bit. The pages are accessed over SSL

One of our testers has determined that if, during a postback, he blocks network access on his PC, and then after a few seconds reconnects, our site becomes excruciatingly slow. Like 30 seconds per page load.

If he hits the refresh button in his browser it stays slow. If he closes the tab, then re-opens it, it becomes fast again.

This behavior happens with both IE 8 and the latest firefox. There are no event log entries on the server when this happens

My question: - Has anyone seen this same behavior? - Does anyone have a theory as to what causes it?
