Aleksei, how (and where) can the "lastModified" be set manually? Directly somewhere in the jar?
I have tested earlier the server side and I know it is really much more faster, and no the client side state saving is not requirement - anyway I like idea of client side state saving, and will use it when possible...
Current released 1.1.3 core has bad npe problem (http://issues.apache.org/jira/browse/MYFACES-1296) and the using of the nightly builds is no option for real project -> Only client side state saving could be used or live in hope that core 1.1.4 will be published before our deadline...

Hi,
is it a need in your requirements to use client side state saving? If
not, try it out to switch to server side setting and test out the
differences.
Have you used the document tags which come along with StreamingAddResource?
Hope that helps,
cheers,
Gerald
