问题 What indicates the end of an HTTP Response, without having a Content-Length header? I've read that in some case, that server closes the TCP connection. But I've witnessed cases that the TCP Connection existed after receiving all the response. So a major problem arises when: There isn't a Content-Length header TCP connection exist after receiving all of the HTTP Response The browser wishes to use the same TCP connection in order to send more HTTP Requests In that case, how the browser knows it

问题 How do I add a custom header to files pylons is serving from public? 回答1: a) Let your webserver serve files from /public instead of paster and configure it to pass some special headers. b) Add a special route and serve the files yourself ala class FilesController(BaseController): def download(self, path) fapp = FileApp( path, headers=self.get_headers(path) ) return fapp(request.environ, self.start_response) c) maybe there is a way to overwrite headers and i just dont know how. 回答2: With a

Content-Range is used in the response, to indicate which bytes the server is giving you (which may be different than the range you requested), as well as how long the entire content is (if known).
