HttpResponse.Filter Property

/** @property */ public Stream get_Filter () /** @property */ public void set_Filter (Stream value)

Not applicable.
Property Value
The Stream object that acts as the output filter.When you create a Stream object and set the Filter property to the Stream object, all HTTP output sent by Write passes through the filter.
The following code example is an ASP.NET page that sets the Filter property to a new instance of the UpperCaseFilter class, a custom Stream class that converts all text that passes through it to uppercase. The information on the request is saved to a text file, and then the Filter property is set. After the response filter is in place, the code calls the MapPath method to get the absolute path to a text file, named TestFile.txt, that serves as the source for the content of the response. The code then creates a new StreamReader object to read the text file from beginning to end, and then calls the Write method to display the content of the file on the page.
