Doesn't the fact that the read on the inputstream returns, imply that there is
actually a timeout, even if it is not returned to the webapp ?
And, to Ronald : if the request is a POST, and it has a Content-length, and you
get an empty parameter map after 20 seconds, can't you just reject the request
as invalid ?
And, curiosity : if you set the Connector timeout to 30 seconds, does your
inputstream then return after 30 seconds too ?
Yes it implies there is a timeout, but it is kind of guessing if it was a
timeout or really an empty ParameterMap for the webapp. This can be
workarounded by always including a dummyvar in the parameters as Christopher
Shultz mentions or checking the Content-Length. But maybe Tomcat can do
something better internally.
Yes if I set the connector timeout to 30 seconds it returns after 30 seconds.
My other workaround is doing a GET ajax in stead of POST. For this case the url
wouldn't be too long for Internet Explorer and than more data is send at once
over the network.
Ronald.
