I have started having problems with our asp.net webform applications running behind a proxy since the user base have upgraded to IE7. Some postbacks seem to drop out and at times it is difficult to make controls on a page raise an event. It appears to be intermittant and I have been told there are issues around using IE7 behind a proxy with post requests. Is this the case and what are the options? Rewite in MVC? Does the issue of post requests behind a proxy remain in IE8?
Any help greatly appreciated.
