Hi! We have been doing some memory-profiling of our site. And found a issue with the class com.opensymphony.oscache.web.filter.RepsonseContent

<a href="https://xwork.dev.java.net/source/browse/oscache/src/java/com/opensymphony/oscache/web/filter/ResponseContent.java?rev=1.1&view=auto&content-type=text/vnd.viewcvs-markup" >com.opensymphony.oscache.web.filter.RepsonseContent</a>.

The issue involves the field named 'bout' declared thus:

private transient ByteArrayOutputStream bout = new ByteArrayOutputStream(1000);
    private Locale locale = null;
    private String contentEncoding = null;
    private String contentType = null;
    private byte[] content = null;
    private long lastModified = -1;

'bout' will after a call hold the cached content. It will also be in the field 'content'. 'bout' is transient but that will not help until we do a restart of the jvm.

I propose that on commit the filed 'bout' be cleared something like this:

/**
     * Called once the response has been written in its entirety. This
     * method commits the response output stream by converting the output
     * stream into a byte array.
     */
    public void commit() {
        content = bout.toByteArray();
        bout=null; //<---- New code
    }

This will in affect half the memory consumption of cached objects!
By the way we used the Yourkit Java profiler it is a great product!

PS If you want to I can submit a patch or try out the change and make sure it works!
