How can I send a POST HTTP request to a server (in Visual Basic 2010) and then receive the reply into a string.
View 1 RepliesI 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.

I 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". [code] Best practice is to incrementally add and remove changes to your entry list instead of deleting/recreating the entire list each time a change is necessary.New entries are placed at the top of the queue for polling and are processed in a LIFO manner.

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.

View 1 RepliesIs 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.
I have gotten this code in python - been going in circles trying to figure out the vb.net equivalent. Will pay somebody for the conversion also.

View 6 RepliesI am currently working on a personal project with hopes of using VB.NET 2008 to connect to my personal forum for use of both authentications into the program and group changes. People in my forum are based on ranks, the ranks are organized via the groups in the forum so if one person gains a rank they need to be taken out of one group and placed into another. With multiple people this is a process and presents a security risk should someone get kicked out but accidently be left in a group giving them access.
