Hi,
Users of Internet Explorer experiences a strange error using my webapp. Sometimes it works, and sometimes the IE says (a translation from Polish):
"It isn't possible to find server or an error of DNS in Internet Explorer".
What is even more confusing, the Mozilla doesn't seem to have such problems at all (it is heavily tested with Mozilla, since I use it for developing webapp).
I'm not quite sure, but I have a feeling that it is caused by multipart forms and SSL used together. Well, it is only suspicion, and I can't really prove it.
Ouch....
IE purportedly has bugs relating to POST over SSL. This was discussed extensively on the Jetty-support mailing list in February (for some reason, searching the gmane archive only turned up 3 articles, but there were a lot more).
See http://support.microsoft.com/default.aspx?kbid=831167 and see if that looks like it might be related...
Unfortunately, I can confirm that this does appear to be related to IE, POST, and SSL. I have quite a bit of experience observing this problem in an application totally unrelated to Cocoon. In that case, it's on Netscape Enterprise Server - not sure where the SSL support comes from if it's not native to NES. The point is, doesn't appear to be related to anything on the server. In our testing, the POST never arrives in some cases. In other cases, it appears to arrive with no POST body (i.e., it's truncated).
The MS KB article above does seem to be related to at least some aspects of the problem - though I need to go back and find out if we applied the advice related to keep-alives.
HTH, Geoff
