Bug #73297 [NEW]: HTTP stream wrapper should ignore HTTP 100 Continue

From: rowan dot collins at gmail dot com Operating system: PHP version: master-Git-2016-10-11 (Git) Package: Streams related Bug Type: Bug Bug description:HTTP stream wrapper should ignore HTTP 100 Continue Description: ------------ This bug report forms part of an attempt to test and fix the implementation of HTTP/1.1 in the HTTP stream wrapper. See http://marc.info/?l=php-internals&m=147544280019519&w=2 A "100 Continue" response is *usually* only sent in response to an "Expect: 100-continue" header, and *usually* only useful with requests which have a body (e.g. POST, PUT). As such, it is unlikely to be encountered by someone sending a GET request using e.g. file_get_contents, but this is not guaranteed. According to RFC 7231 section 6.2: > A client MUST be able to parse one or more 1xx responses received > prior to a final response, even if the client does not expect one. A > user agent MAY ignore unexpected 1xx responses. However, the code currently treats these statuses as errors: > HTTP request failed!
