When installing a java based application however, the install fails to complete and a connectivity error is reported on the client after 60 seconds

Application install seems to download huge number of files with .deploy extension that appear to contain java classes

Malware scanning causing delayed responses for .deploy objects

Proxy sends back scanned payload one byte at a time, causing huge delays.

Additional Information

PCAPs showed the GET/CONNECT requests from the user and 200 OK responses

During the exchange, the 200 OK responses start off with full TCP payloads of 1460 (1500 ethernet packet minus 20 byte IP and 20 byte TCP header). As the install goes on, we see the payload in the responses drop to 1 byte in size.

These one byte packets cause huge delays with the responses - we send 1460 packets instead of one!
