note 56049 modified in function.fsockopen by vrana

I have found, when using fsockopen() and the POST method, that using HTTP/1.1 is VERY significantly slower than HTTP/1.0 (at least for the server I'm querying, an Orion-based server). Also, using cURL tended to be faster than fsockopen(), though only slightly. For example, here was a recent set of data (for the same exact request in each case): cURL: 4.2sec fsockopen() HTTP/1.0: 4.9sec fsockopen() HTTP/1.1: 19.9sec (!) I'm not sure why this was occurring. Perhaps it has something to do with the Orion server, which I have little experience with. However, it was not a fluke, and I double-checked the code to make sure there were no errors. EDITORS NOTE: HTTP/1.1 uses persistent connection causing this delay. Use "Connection: close" header to disable it. --was-- I have found, when using fsockopen() and the POST method, that using HTTP/1.1 is VERY significantly slower than HTTP/1.0 (at least for the server I'm querying, an Orion-based server).
