When you call the Response.ClearHeaders method in a custom HTTPModule that is registered with PreSendRequestHeaders, extra characters are returned. This problem occurs only on the first request or the first time that you make this call after you compile the application.
For the first request of a page, the compiler tries to do a batch compile and takes a different code path in the Response.Flush method. Later in the code, when you try to add chunkprefix and chunksuffix characters, they appear as extra characters in the output.
