Send POST Body With HTTP Request?
May 3, 2010I have used the WinHttp.WinHttpRequest object in VB6 to make HTTP POST requests many times. It works great: .Open the URL, then .SetRequestHeader (however many are needed) and then .Send the body. The .Send method makes the actual connection and sends everything to the server at once.How to I emulate this behavior in .NET? The examples I've tried with System.Net.HttpWebRequest open a stream with .GetRequestStream() and then write the body to the stream. Unfortunately, the server is responding immediately to the .GetRequestStream method and therefore never sees the POST body.I am obviously trying to connect up some legacy stuff here, but am having a hard time Googling the problem or finding another approach in .NET.

View 1 RepliesSend A POST Request To Add Some Content To An API Box
Nov 11, 2010I am trying to send a POST request to add some content to an API box. The rules are that the body format should be XML(values must be XML-escaped), HTTP Method (post), requires authentication(yes), request content(content-type: "application/xml".

Apr 6, 2011When you search on google most of the examples are very vague, hopefully this thread can make it to the top and will help someone looking for the same info.to explain the code what it does is create a long string by concatenating all the values together stores it in the variable finalString and then hashes the string using the SHA5 algorithm. Then its supposed to send the string (finalString) as a post request to the url.The server im sending it to reads it this way and sends a response. [code]
View 1 RepliesMake The Http "POST" Request To The Specific Spot?
Mar 18, 2011I am trying to write this program that logs into this website. Now I figured out how to make the http "POST" request to the specific spot on the page which returns a "Successfully logged in" afterwards but once I make a request to another part of the page, it asks me to login (I look at the source code). I have been messing with Fiddler and I compared the a POST from my webbrowser to a POST from my program. I found the following lines to be in my browser POST and not in my program post:

I am assuming this has something to do with the cookie that I am suppose to get to be able to tell the website that I am logged in. If someone could point me in the right direction that would be great. I dont use XMLHTTPREQUEST in my program. I found it earlier on the msdn website but now I cant find a reference to it.I am also not good with term names and I just started learning VB and don't know much about cookies/HTTP requests and such, but that is why I am trying to learn.

.net - Send Response To Asp.net Webform Request Via Other Server
Jun 17, 2011I have two web servers with public IPs, for example Server1 with IP 111.111.111.111 and Server2 with IP 222.222.222.222. see the picture:
There is an asp.net webform at Server 1. My intention is:
For every http request to that webform in Server1, the Server1 just pass the request's information to Server2 for logic processing and subsequently Server2 sends the response back to client (i.e. normal browser)
My questions are:
What information that Server1 needs to pass to Server2, so that Server2 able to send response back to client? note that at Server2, there is a TcpListener instance. This TcpListener instance acting as receiver for that webform request information from Server1. What is the suitable object (i.e. the class in System.Net or related namespace such as System.Net.Sockets) at Server2 for sending response back to client? Suitable here means able to meet my intention.

View 1 RepliesGet The Second Chunk After Receiving The First One Since It Is Within The Same HTTP Request ?
Jun 17, 2011Is there any way we could get directly say the 1000 characters after the first 5000 characters, skipping everything before that after sending in an HTTP request to an HTTPS page using either GET or POST in VB.NET? The reason why I ask this question is because in one of the webpage I am trying the get through my program, the website is sending response data in chunks with the first chunk containing some javascript garbage that I have no interest in, the only data I care is in the second chunk and
how to get the second chunk after receiving the first one since it is within the same HTTP request.It would save some time and Internet traffic if I can skip the first chunk that I do not need.Is that possible or I am just day dreaming?
ADDED: Here is how a typical header of the response I am getting from the webpage I am trying to get:
Date: Mon, 20 Jun 2011 13:21:56 GMT
Set-Cookie: JSESSIONID=1AF1AF9EF936E1CB2FA85B750EDC67C4; Path=****some path******; Secure
Content-Type: text/html; charset=ISO-8859-1[code].....
Not sure if that helps, but as you can see, the chunk size is not visible to me, there is no "Trailer" in the header as well.
