Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major

--> https://issues.apache.org/bugzilla/attachment.cgi?id=27291

I am using Tomcat 6.0.20 on Ubuntu 10.04 and have written a simple
TomcatWeatherServlet as presented in
http://www.ibm.com/developerworks/web/library/wa-cometjava/ I modified the
servlet to stream weather feed to multiple curl clients. I am using curl 7.21.6
as my client.
When I run curl -i -k -v -trace https://<IP_Addr>:8443/Weather from the
command-line I get the following response for the first few times:
<code>
$ curl -i -k -v -trace https://<IP_Addr>:8443/Weather

Observe that Content-Length is 0 in the response. Also when I do get the
expected response which is,
<code>

I get Transfer-Encoding as chunked and no Content-Length.
On Server logs I get for the error are:
16:40:16.916 INFO http-8443-exec-3 TomcatWeatherServlet:41 - Begin for
session: BDD6B1808161F1DA99D5D3207F1A719B
16:40:16.959 INFO http-8443-exec-4 TomcatWeatherServlet:48 - End for session:

BDD6B1808161F1DA99D5D3207F1A719B
This was working when I was on HTTP. I have tried to debug this for a lot of
time w/o success. Also I get two END events instead of one as seen in the Logs.
