Maximum request length exceeded

Question

Hi, all

 

When I am uploading a high-quality image in asp .net web application, the system gives error maximum request length exceeded.

 

I try this solution

 

<system.web> <httpRuntime maxRequestLength="1048576" /> </system.web>

 

but when I change in web config file and upload this solution on the server, my web application gives error 500 internal server error.
