We have a website coded in ASP at: [url removed, login to view]
The website currently is completed however, we noticed that there is a multithreading error if two or more people try to make a purchase using "Pay Now" at the same time. It only allows the first order to go through and then denies the rest in this case. This seems like the website is trying to verify the payments or process them simultaneously so therefore it cannot.
To fix this we believe it would require putting a critical section around that specific code that is sharing across the threads so it does one at a time. We are not asp coders however, please let us know what the cost would be and your timeframe to fix this issue.
Please make sure to message us along with your bid and let us know if you specialize in ASP and also show us past work you have done with ASP.
Please note: We use Paypal Website Payments Pro as our merchant account to verify/process the payments, we believe this is irrelevant to fix this issue but wanted to include it incase this information is helpful/necessary.

Hi I suppose that your critical section idea is quite correct. However it might be some other initialization issues. I have quite good and relevant experience in that area. All the best. Alexei
