not able to use asp.net's compression utility

Hi, it seems that the asp.net 2.0compression utility is not working on your servers:


Response.Filter = new System.IO.Compression.GZipStream(Response.Filter,System.IO.Compression.CompressionMode.Compress);


Is this not supported? (I saw an earlier post about this, but the response wasn't clear on wether this is supported or not).


Thanks.

 

It should work fine.Whats the error Message?

Following is a sample code snippet for using the compression and decompression functions:

Private Sub Compress(ByVal source As String, ByVal destination As String)
Using sourceStream As System.IO.FileStream = System.IO.File.OpenRead(source)
Using destinationStream As System.IO.FileStream = System.IO.File.OpenWrite(destination)
Using compressedStream As New System.IO.Compression.GZipStream(destinationStream, System.IO.Compression.CompressionMode.Compress)
Dim data As Byte() = New Byte(sourceStream.Length - 1) {}
sourceStream.Read(data, 0, data.Length)
compressedStream.Write(data, 0, data.Length)
End Using
End Using
End Using

End Sub

Private Sub DeCompress(ByVal source As String, ByVal destination As String)
Using sourceStream As System.IO.FileStream = System.IO.File.OpenRead(source)
Using destinationStream As System.IO.FileStream = System.IO.File.OpenWrite(destination)
Using decompressedStream As New System.IO.Compression.GZipStream(sourceStream, System.IO.Compression.CompressionMode.Decompress)
Dim data As Integer
While (data = decompressedStream.ReadByte()) <> -1
destinationStream.WriteByte(CByte(data))
End While
End Using
End Using
End Using
End Sub

It is available, yes. The earlier thread demonstrated that it works and it turned out that the original poster had a buggy Firefox plugin that was not reporting the compression, so he thought it was not working.
