New Revision: 1709690
URL: http://svn.apache.org/viewvc?rev=1709690&view=rev
Log:
Need local settings for the window size the client is expected to use to
communicate with Tomcat, not the remote settings.
Add some comments to (hopefully) reduce future errors of this nature.
This fixes a CI failure.
