I am trying to send an HTTP Request to a server using a POST method. The problem comes from the PostData, which needs to be in Bytes form to be used by the UploadData function.

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.
View 2 RepliesI have written server code in vb.Net. I want it to read to variables sent by another server's HTTP 'GET' request. For example the first server will send this URL [URL]msgid=$messageid where the values to be used by my server are sender, receiver, msgdata, recvtime and msgid I have written my code but it only reads the address sent by the http server and locates for the file in the server's root directory. I want the server to be reading the variables sent by the other server using the HTTP 'GET' request. My code is shown below
' the web server only accepts get requests.
If Mid(LCase(sbuffer), 1, 3) <> "get" Then
'if not GET request then close socket and exit

View 1 RepliesI 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.
View 2 RepliesWhen 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]

I 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.

I 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 4 RepliesHow to find the best way to develop a way to send a meeting request with a .Net application. I'm beginning in .Net development. The thing I'd like : the user has a form where that he can fullfill with the info about the meeting. Then, the server creates a .ics file with those information. I'd like next to suggest the user to send this meeting request. So, is it possible to create a mailto with an attachement that's located on my server? Is it the best way to handle this problem? Ain't there any other possibility to interact between an app and Outlook? I'm developping in VB.Net for a web application using the framework ASP.NET MVC 3.
