--- Comment #18 from Ken Sharp kennybobs@o2.co.uk 2009-04-30 20:41:29 --- Under the latest gitwine I compared +gecko logs for connecting using the Casino client (which attempts a connect to http://ocsp.thawte.com for a certificate) and simply using "wine iexplore http://ocsp.thawte.com".
The second method reports: 27[1db48a8]: recv -> 2, error = 0, os error = 0
Whereas through the app reports: 65[26ac870]: recv -> 3, error = -5998, os error = 0
At the exact same point of connection. EC terminates the connection shortly after this, whereas "iexplore" continues to load the page (which appears blank anyway) with security.
I'll look at this further tomorrow.
