         com.opensymphony.oscache.web.filter.SplitServletOutputStream

All Implemented Interfaces:
Closeable, Flushable

Extends the base ServletOutputStream class so that the stream can be captured as it gets written. This is achieved by overriding the write() methods and outputting the data to two streams - the original stream and a secondary stream that is designed to capture the written data.

Field Summary
OutputStream	captureStream
OutputStream	passThroughStream

Constructor:

Constructor:
public SplitServletOutputStream(OutputStream captureStream, OutputStream passThroughStream) { this.captureStream = captureStream; this.passThroughStream = passThroughStream; } Constructs a split output stream that both captures and passes through the servlet response. Parameters: `captureStream` - The stream that will be used to capture the data. `passThroughStream` - The pass-through `ServletOutputStream` that will write the response to the client as originally intended.

 public SplitServletOutputStream(OutputStream captureStream,
    OutputStream passThroughStream) {
                                                   
        this.captureStream = captureStream;
        this.passThroughStream = passThroughStream;
}

Constructs a split output stream that both captures and passes through the servlet response.

Parameters:

captureStream - The stream that will be used to capture the data.

passThroughStream - The pass-through ServletOutputStream that will write the response to the client as originally intended.
