An extremely useful blog post for LoadRunner users (or just for education): Tips for browser emulation in network-level scripts: http://bit.ly/10asaqW

Also a very overlooked option is that network buffer setting in VUSER options. In order to avoid some really nasty gzip/deflate failures as well as other issues under heavy load injection, we've had to match up the tcpip sliding window size and os buffers with the script buffering setting. In our case it was 256kbytes wide. Once we did that scripts ran beautifully through our proxy as well. The default is 12kbytes.
