Eric,
Thanks for your reply. Here is some more information.
The file being served here, is 121MB in size, is actually being served by tomcat. I am assuming that range header will be passed to tomcat and it will take care of serving the required range. Is this correct?
OTOH, the range requested by client varies from "9392444-" to "122206258-" which means client is requesting last 112MB to 4MB chunk of the file. There were 250 of such requests in an hour from one single user to one single tomcat and total 1500 such similar request to same file from 7 other users during the same hour! Response size varies from 196600 to 663544.
This is causing our tomcat thread count to go high which is resulting in poor overall site performance.
We are suspecting that users are using some kind of download manager and that is misbehaving, but before concluding that I wanted to check if this is valid behavior for Apache/Tomcat.
Thanks,
Sameer

Apache doesn't buffer a response to satisfy a range request, it
responds legally with the entire response instead.
(it doesn't try too hard to see if the range is "easy" to satisfy)
