[mod_python] gzip and conditional get

An example of output compression.

import gzip

def getWriter(req):
    try:
        if req.headers_in['Accept-Encoding']=='gzip, deflate':
            return gzip.GZipFile('','wb',9,req)
    except:
        pass
    return req

def processRequest(req):
    writer = getWriter(req)
    writer.write(header)   
    writer.write(content)
    writer.write(footer)
    writer.close() # Good practice to do this. It does not try to close req
object
    return apache.OK

If you want to use it with Cheetah or another templating engine, most of them
accept writers and you will be better off passing the writer to them for quick
response.
