I work on MVC.net application. I make asynch requests to my controller via jQuery. Below you can see these requests in fiddler (all of them are fired in a specific sequence).

num result protocol Host URL

2929 200 HTTP somesite.com:1936 /DynamicTables/SaveCurrentRowsState

2930 200 HTTP somesite.com:1936 /DynamicTables/AddRows?key=30060d39-7531-41a2-8d40-4c53ec34d6ff&rowsCount=5

2930 200 HTTP somesite.com:1936 /DynamicTables/GetNextPage?key=30060d39-7531-41a2-8d40-4c53ec34d6ff&newPageNumber=21&rowsPerPage=30

But server handles these requests in an another sequence (I placed breakpoints on start of each of these methods on the server and so in order to check this sequence). So, actual sequence is:
1) AddRows
2) SaveCurrentRowsState
3) GetNextPage

It seems like asp.net spends different time to handle these requests before it faces my breakpoints.
Could somebody help me why it is possible? Is there any way to avoid this situation?

Thanks,
Egor

    If you are sending a series of async messages to the server, then there is no guarantee in what sequence they will be processed. If you need that level of control, either bundle them all into a single call to the server, or call them synchronously.
