Use multiple response filters in ASP.NET

is there any way to use multiple response filters in ASP.NET?

HttpContext.Current.Response.Filte开发者_Python百科r = MyFilter1
HttpContext.Current.Response.Filter = MyFilter2

This code is clear, can't work. It overrides the current filter with the new instance.

So, what are your best practice for this scenario.

Thank and best regards.

A filter is a Stream that writes to another Stream. Usually you construct a filter like this:

response.Filter = new MyStream(response.Filter);

To use multiple filters, you do the same:

response.Filter = new FirstFilterStream(response.Filter);
response.Filter = new SecondFilterStream(response.Filter);

Only a single response filter can be applied, so you need to aggregate all the work in this filter. Here's an example how this could be achieved:

Response.Filter = new TrimStream(new CompressStream(Response.Filter));

This way you can combine multiple streams.
