If you will run an ajax script as www.geoseo.com , you will easy see that there is a limit of max. 4 connections /host... Does anybody known how to override this limit?! It's seems to applies for all IPs, even for downloads! You can't have more then 4 open downland at the same from the same host... I also saw that http://www != http:// ... Is this an windows limitation ? or an apache limitation ?! how to over-ride it?!
That is a server side limitation - you cannot change it unless it is your server. That site also sucks compared to SEOlogs.com tools.
Softgroups. I don't know which version of Apache you are running, but this is most likely what you are looking for. http://httpd.apache.org/docs/1.3/mod/core.html#maxclients
