Hello all, 

I am using Squid 3.4 to inspect content that heads out to the cloud from 
enterprise. I have two c-icap filter that does the content inspection. 

Observation: 
- Upload 3000 1M files to cloud passes through successfully. 
- Upload 300 40M files to cloud results in multiple failures. Some of errors: 
400 Bad Request, Request Timed out.. 

Tcpdump of the 40MB file upload tests indicate the following:
- Boto client used to upload sends packet to squid proxy. 
- Proxy does not acknowledge. 
- Client sends the data again at least 6 times, Squid does not respond. 
- After 20-25 seconds of this (where Squid did not send any data to cloud), 
Cloud storage vendor returns a "BAD Request" response. 

Uploading 300 files seems to be a load that should be manageable by Squid. Can 
anyone guide me on how to optimize Squid for the above scenario? Are there any 
performance parameters that I can tweak so Squid handles this correctly?

Thanks, 
Saravanan
