Roberto,
Thanks for the reply. I agree, I should be serving static files (*.js,
*.css, etc.) from the webserver, I guess I don't know how to do that;
get Apache2 (what we're using) to serve up the files from the /public
folder inside my Pylons project. Got any pointers, or does this fall
under the "Web Serving 101"?
The rest of this response is the contents of the gzip middleware I
mentioned. This is taken almost verbatim from "The Definitive Guide to
Pylons" book.
import gzip
import StringIO
class GzipMiddleware(object):
'''This class implements gzip compression for *.js and *.css files
delivered by the pylons applications'''
def __init__(self, app, compresslevel=9):
self.app = app
self.compresslevel = compresslevel
def __call__(self, environ, start_response):
if 'gzip' not in environ.get("HTTP_ACCEPT_ENCODING", ""):
return self.app(environ, start_response)
if environ["PATH_INFO"][-3:] != ".js" and environ["PATH_INFO"]
[-4:] != ".css":
return self.app(environ, start_response)
buffer = StringIO.StringIO()
output = gzip.GzipFile(
mode="wb",
compresslevel=self.compresslevel,
fileobj=buffer
)
start_response_args = []
def dummy_start_response(status, headers, exc_info=None):
start_response_args.append(status)
start_response_args.append(headers)
start_response_args.append(exc_info)
return output.write
app_iter = self.app(environ, dummy_start_response)
for line in app_iter:
output.write(line)
if hasattr(app_iter, "close"):
app_iter.close()
output.close()
buffer.seek(0)
result = buffer.getvalue()
headers = []
for name, value in start_response_args[1]:
if name.lower() != "content-length":
headers.append((name, value))
headers.append(("Content-Length", str(len(result))))
headers.append(("Content-Encoding", "gzip"))
start_response(start_response_args[0], headers,
start_response_args[2])
buffer.close()
return [result]
