a. Use a full blown webserver like apache or nginx and configure it to gzip content on client request b. Use a simple wsgi gzipping filter.
For b. there is a simple and fast enough filter in wsgitools package. You can use it in anyserver.py or any place when calling the wsgi application as: from wsgitools.filters import WSGIFilterMiddleware, GzipWSGIFilter # filter web2py wsgi application wsgiapp = WSGIFilterMiddleware(gluon.main.wsgibase, GzipWSGIFilter) 2013/4/22 Derek <[email protected]> > Unless you are using IE lower than 5.5, all clients support gzip.
