How do I get execution status through Ajax when ASP.net threads bulk Import data

Objective

Recently because of the work encountered a demand, need to do a bulk import function, but a long time to run no feedback status, it is easy to see the impatient, produce all kinds of conjecture! In order to solve the heart barrier, wrote this function.

Through the thread to execute the import, and put the state of execution into session, both share the execution state, through the AJAX call session execution status, so as to achieve feedback import state function!

The code is as follows

OK, sharing is complete!
