First of all I think this is a common problem, but cannot find a really good solution;
We have a web application, some of its request takes more than a minute. In the mean time we should be able to do more job with that application (for instance a simple lookup from database) but web server does not respond to any request until the previous one finishes.
As we are starting to develop this application from scratch we can embed everything including the option to change the web server also. Which web server or which methodology do you think we should follow ?
By the way we will use PHP for this.
Thank you very much, Baris
