I think that is HTTP/1.1 for you ... but the details are a little foggy

Ladies and Gentlemen, I have created an html document that contains several <Iframe>s that all refer to the same JSP page. The JSP simply waits(Thread.sleep()) 5 seconds and then returns some text. When I open the html document in either IE or Mozilla after 5 seconds I see the first two iframes load, then 5 seconds later, I see the next two, etc. I am using the default config params on tomcat 5.0.28 on Win XP Pro. If I understand them correctly, I should have between 25 (minSpareThreads) and 150(maxSpareTreads) threads available. Why do the requests wait for the previous to complete as if there are only two threads handling the requests? In my research, I have noticed that connecting from other machines, I get two concurrent requests per machine. For example, if I open the html page on three machines simultaneously, it appears that I have 6 threads in tomcat working. But I am always restricted to two concurrent requests per client. I have also noticed that if I use both IE and Mozilla on the same machine, I am able to get at most 4 consecutive requests. Again 2 requests from each browser. If I open 3 IE browsers on the same machine I see the updates happen two at a time across all the browsers. Is there some piece of configuration that I am missing? Where is this two concurrent requests coming from?
BTW it does not appear to be the browser that is dispatching only two requests. I can add any number of additional Iframes pointing to non-tomcat sites and they seem to begin loading immediately.
Thanks,
