问题
Recently i found that i am getting EConvertError after calling IDHTTP.GET. I analyzed the traffic and saw the expire date on the cookie is 2000. Now my question is how to bypass this. I am using the Indy10 that is present in XE3. I know Indy follows strict standard about cookie handling but shouldn't there be a feature to turn this off ?

The offending date/time string is not coming from a cookie, as the TIdCustomHTTP.ProcessCookies()
, TIdCookieManager.AddServerCookies()
, and TIdCookie.ParseServerCookie()
methods are not included in the call stack you showed. It is actually the Last-Modified
header that is at fault. Facebook is sending an ISO 8601 formatted date, which is not supported by the HTTP specs. That is a bug in Facebook's HTTP server. They should have known better than to use a non-conforming format for an HTTP date header. That bug needs to be reported to Facebook so they can fix it. In the meantime, I have checked in an update to the latest Indy SVN snapshot so TIdHTTP
can now parse ISO 8601 dates.
