If I want my static .html/whatever files to be gzip'd when the client supports it, does that mean I have to serve them myself and can't use static.File?

Not necessarily, since you can handle the gzip operation above the level of the static.File resource, though you may need to get slightly more involved in handling the request than you would otherwise. Here's what I created for one of my servers that uses twisted.web in order to support the gzip encoding (note some debugging prints are still present). First, I have a wrapper for a Request object that will handle gzipping any data generated for the client that the Request object generates, including with a producer/consumer model such as that used by static.File. - - - - - - - - - - - - - - - - - - - - - - - - - import struct import zlib class GzipRequest(object): """Wrapper for a request that applies a gzip content encoding""" def __init__(self, request, compressLevel=6): self.request = request self.request.setHeader('Content-Encoding', 'gzip') # Borrowed from twisted.web2 gzip filter self.compress = zlib.compressobj(compressLevel, zlib.DEFLATED, -zlib.MAX_WBITS, zlib.DEF_MEM_LEVEL,0) def __getattr__(self, attr): if 'request' in self.__dict__: return getattr(self.request, attr) else: raise AttributeError, attr def __setattr__(self, attr, value): if 'request' in self.__dict__: return setattr(self.request, attr, value) else: self.__dict__[attr] = value def write(self, data): if not self.request.startedWriting: print 'GzipRequest: Initializing' self.crc = zlib.crc32('') self.size = self.csize = 0 # XXX: Zap any length for now since we don't know final size if 'content-length' in self.request.headers: del self.request.headers['content-length'] # Borrow header information from twisted.web2 gzip filter self.request.write('\037\213\010\000' '\0\0\0\0' '\002\377') self.crc = zlib.crc32(data, self.crc) self.size += len(data) cdata = self.compress.compress(data) self.csize += len(cdata) print 'GzipRequest: ' \ 'Writing %d bytes, %d total (%d compressed, %d total)' % \ (len(data),self.size,len(cdata),self.csize) if cdata: self.request.write(cdata) elif self.request.producer: # Simulate another pull even though it hasn't really made it # out to the consumer yet. self.request.producer.resumeProducing() def finish(self): remain = self.compress.flush() self.csize += len(remain) print 'GzipRequest: Finishing (size %d, compressed %d)' % (self.size, self.csize) if remain: self.request.write(remain) self.request.write(struct.pack('
