limit concurrent connections with squid

I have a Linksys SRW2048 switch and the UI fails under IE[789] because it uses too many concurrent connections for the switch to handle. I can use IETab in Firefox which works because it indirectly limits the number of concurrent HTTP requests, but that isn't always a solution. I have a squid proxy running on a linux router though, so I was hoping I could limit the number of concurrent connections. The docs tell me I can limit them by using a deny but that will result in the connection failing rather than simply being delayed until other connections are complete. Any suggestions? I'll use netfilter to drop new connection requests if I can't figure it out using squid. Thanks James
