Supporting HTTP 100 Continue with PHP

阅读更多关于 Supporting HTTP 100 Continue with PHP

问题 I'm working on a PHP webapp that accepts large POSTed file uploads from specific clients and would like to accept or reject these uploads (based on various headers and other factors, not just size) before the file is uploaded by using HTTP/1.1 100 Continue. Some quick background from HTTP/1.1 spec 8.2.3: The purpose of the 100 (Continue) status (see section 10.1.1) is to allow a client that is sending a request message with a request body to determine if the origin server is willing to accept

问题 Is it possible to send "100 Continue" HTTP status code, and then later some other status code after processing entire request using Java Servlet API (HttpServletResponse)? I can't find any definitive "No" answer, although API doesn't seem to support it. 回答1: I assume you mean "100 Continue". The answer is: no, you can't (at least not the way it's intended, as provisional response). In general, the servlet engine will do it automatically, when the request requires it. Of course this makes it

ASP.NET: Overriding IIS response to “expect 100” header?

问题 I have an ASP.NET application that receives requests from a client software and the request headers contain a "request 100-continue". I want to override IIS auto-response to request-100 header so that I can use the other headers to authenticate the user (or not) and send a proper response depending on the state (100 continue for authenticated obviously) or a proper error message. 回答1: The way we have accomplished this type of thing, and I believe a common approach is to create an HTTP Module

问题 I'm implementing a REST API using ASP.NET MVC, and a little stumbling block has come up in the form of the Expect: 100-continue request header for requests with a post body. RFC 2616 states that: Upon receiving a request which includes an Expect request-header field with the "100-continue" expectation, an origin server MUST either respond with 100 (Continue) status and continue to read from the input stream, or respond with a final status code. The origin server MUST NOT wait for the request

问题 Many libraries include Expect: 100-continue on all HTTP 1.1 POST and PUT requests by default. I intend to reduce perceived latency by removing 100-continue mechanism on the client side on those requests for which I know the expense of sending data right away is less than waiting a roundtrip for 100-continue, namely on short requests. Of course I still want all the other great features of HTTP 1.1, thus only I want to kill Expect: 100-continue header. I have two options: remove expect header

Is it possible to send "100 Continue" HTTP status code, and then later some other status code after processing entire request using Java Servlet API (HttpServletResponse)? I can't find any definitive "No" answer, although API doesn't seem to support it. Julian Reschke I assume you mean "100 Continue". The answer is: no, you can't (at least not the way it's intended, as provisional response ). In general, the servlet engine will do it automatically, when the request requires it. Of course this makes it impossibe for the servlet to prevent sending the 100 status -- this issue is a known problem
