Classic ASP response buffer limit exceeded

Question

Classic ASP response buffer limit exceeded

Ori Gil 6

Hi!
I'm moving my classic ASP application from IIS 8.5 on Windows Server 2012 to IIS 10 on Windows Server 2019.

I installed the application and configured it correctly however in some pages with searches which result in a big size response I'm getting the error:
Error is : Response object error 'ASP 0251 : 80004005'
Response Buffer Limit Exceeded

As suggested in many threads in other websites and forums I tried changing the setting of Response Buffering Limit to the max of 64MB but it doesn't solve my issue.

Any ideas or directions for solving my issue are appreciated!

Hi @Ori Gil ,

Did you use Response.BinaryWrite in code? Document has recorded this error and provided a solution. You can refer to the docs. It seems that the search result in response is too large, more than the 4MB, maybe even 64MB.

To resolve this issue when you use the Response.BinaryWrite method and ASP buffering is turned off, verify that the data that is returned to the client is not larger than 4 MB. If the response is larger than the 4-MB default value, this size frequently causes a poor user experience. The Web browser must receive the large response over the network. Then, the Web browser must parse an display a large HTML response.

I want to know how you move the application to IIS. If possible, try to use visual studio publish it again and deploy to IIS10 directly.
