Hi Jean,

I am sorry to bother you again. Do you any time frame by which this feature
can be implemented in 1.0.23. We are kind of struck and could not proceed
due to this.

Also, could you please let us know which version of jar contains
DeliverResponse.setFinished method so that our team look to try of work
around. We have downloaded 3 or 4 versions of grizzly jars and could not
find this method in them.

I appreciate your help.

Thanks,
Somesh
