Hi Ben,
I am not sure what exactly this parameter can do.But this is based on the article here
http://cafe.bevocal.com/docs/faq/faq.html Iam usign a voice browser to fetch the docs from tomcat and see bad fetches being thrown.
Based on the above link I mentioned,it looks like bad fetches can be reduced by disabling chunking.
If you have any insight into this,do let me know.
Thanks,
Kartik
