Redirect response output using VBScript in ASP classic

In a simple .asp file, any content outside the tags is <% %>sent directly to the output buffer. In addition, the expression in the tags <%= %>is evaluated and sent to the output buffer.

I want to redirect it so that in some context that I set, the result of these two constructs is instead sent to a buffer that I control. If possible, I would like to be able to do this dynamically so that I can redirect the output to different buffers at runtime.

The problem is open, largely because I will plan what I create around this solution. I could use any method that exists to capture this output. Performance and ease of use are not core considerations.

This is a continuation of this question in which I am trying to find one possible solution that does not work.

Essentially, you are trying to rewrite the ISAPI asp.dll filter. If you really wanted to do this, you can try writing a DLL wrapper around asp.dll, which overrides the WriteClient function . It will not be easy and will ask a question about what you are trying to accomplish.

<html>
<%=OutputHtml()%>

good for <% =%> you could write your own function:

function [=](val)
    response.write val
    ' do anything you want with val
end function

another thing is impossible to think. but you can use the <% =%> construct for every output you want to redirect ...
