Hi All,
I am facing issues with handling several request in parallel from same user.
When I submit one job and then simultaneously try to open my server
homepage in new tab, it waits until first one finishes. I went through some
earlier answers regarding this and came to know that there is some issue
with session but I am not aware how to resolve this using session.forget()
or where to put this in my code. I tried to put this in one function in my
code but it doesn't allow my job to run further.
I have also used session variable in my views/html file...
I have attached my sample code...
Thanks
