HTTP: Illegal chunked encoding

由 岁酱吖の 提交于 2019-12-12 10:02:48
问题 I have a .NET client-application which uses a third-party library to access a server via http. The library throws the following error: The server committed a protocol violation. Section=ResponseBody Detail=Response chunk format is invalid The software is already installed dozens of times, so i think it must be an issue in the customers system, my suspicion is the proxy between. I have used Fiddler to get a first hint. While sniffing Fiddler notice a protocol violation: Illegal chunked

What makes conditional GETs “conditional” if the resource is obtained in the initial request?

由 最后都变了- 提交于 2019-12-11 23:07:54
问题 Breaking down what makes a conditional GET: In RFC 2616 it states that the GET method change to a "conditional GET" if the request message includes an If-* ( If-Modified-Since , If-Unmodified-Since , If-Match , If-None-Match , or If-Range ) header field. It then states: A conditional GET method requests that the entity be transferred ONLY under the circumstances described by the conditional header field(s). From my understanding this is saying it will only return the data being requested if

How do i send a POST request without Transfer Encoding:chunked from Jersey ReST Client 2.22.2

由 99封情书 提交于 2019-12-10 23:27:30
问题 When i send a POST request through Jersey ReST client it's automatically using Header transfer-encoding: [chunked] . Is there any way to force use of content-length: instead of transfer-encoding.? WebTarget webTarget = client.target(connection.getServerUrl()); Invocation.Builder builder = webTarget.request(MediaType.APPLICATION_XML); Response response = builder.post(Entity.xml(requestBroker)); After adding Content-Length property too the behavior is same WebTarget webTarget = client.target

New Line definition for HTTP/1.1 headers

问题 I have an embedded system that makes a HTTP POST request, however I know that the headers must have a format. In this case I have this request: POST / HTTP/1.1\n Host: 192.168.1.15\n Connection: close\n Content-Length: 44\n Content-Type: application/json\n \n {\n "command": "snapPicture",\n "selfTimer": 0\n } I want to avoid any kind of error while I send this request. Strictly talking, is it correct use \n to tell new line or should be \r\n ? Any suggestion about this request format? Thanks

Can Tomcat accept HTTP 1.1 requests without a Host header?

问题 HTTP 1.1 states: "A client MUST include a Host header field in all HTTP/1.1 request messages" However, the machines I am working on send out this exact POST (containing coordinates), which I do not have access to change: POST /touch HTTP/1.1 Content-type: application/x-www-form-urlencoded Content-Length: <n> x=<int x>&y=<int y> Tomcat 7 immediately responds with 400 Bad Request due to the lack of a Host header field, and the POST never gets to my servlet. Is there any way I can avoid this

Does empty “Expect:” header mean anything?

由 久未见 提交于 2019-12-05 21:50:37
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

HTTP/1.1 response to multiple range

由 扶醉桌前 提交于 2019-12-04 02:04:15
While writing my HTTP/1.1 server, I get stuck dealing multiple ranges request. Section 14.35.1 of RFC 2616 refers some examples but doesn't clarify server behaviour. For instance: GET /some/resource HTTP/1.1 ... Range: bytes=200-400,100-300,500-600 ... Should I return this exact sequence of bytes? Or should I merge all ranges, sending 100-400,500-600 ? Or sending all in between, 100-600 ? Worst, when checking Content-Range response header (Section 14.16), only a single range may be returned, so I wonder how would a server response to example in Section 14.35.1 bytes=0-0,-1 !!! How should my
