    <p><strong>Task</strong>: I'm using static classes, so everyone shares data that's been already loaded. If someone makes a change, that request will put an item in a list with an incremental ID, and my idea would be that every client has it's version on client side and requests if there's any change.</p> <p><strong>My solution</strong>: For this I use a $.post with a timeout of 5000ms and sending the client version, on server side I have a 500 cycle for loop which checks if there's something newer and breaks the loop, returns the changes and have a 10ms Thread.Sleep in every cycle so it wouldn't hog the cpu. Either if on the client it times out, has an error, I call the post again, if it succeeds I process the return data, than call the post again. This way I always should get the changes almost instantly without an overwhelming number of requests, and if something fails, I only need to wait 5secs for it to resume.</p> <p><strong>My problem</strong> is that when this loop runs, other requests aren't handled. With asp.net development server, that's okay, because it's single threaded. But that's also the case with win7hp iis7.5.</p> <p><strong>What I tried</strong>: Set it in the registry (HKLM\SOFTWARE\Microsoft\ASP.NET\4.0.30319.0\MaxConcurrentRequestsPerCPU), increasing the worker threads for the application pool, updating the aspnet.config file with maxConcurrentRequestsPerCPU="12" maxConcurrentThreadsPerCPU="0" requestQueueLimit="5000" settings, and I also read that my win7hp should be able to use 3 threads. I also thought it's an optimization, that I use same variables in one request so it queues the others, so I commented those lines, left the for loop with the sleep only, but same result.</p>

    3. COHow many users do you want to support simultaneously? (1-10, 10-100,100-1000, >1000) How big is the data set that you are passing to the client? does "sending the client version" mean the "incremental ID" or the whole data set?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
