I want a PC to operate as a mini HTTP web server that can receive requests from local (WIFI) devices. I know how to resolve the addresses so that the URL of the PC will be known on the WIFI network, but I'm not sure how to get the PC to act as a HTTP server.

I have created a few months ago a simple tool in vb.net, that sends an xml code to server, and that server sends response after a while. Everything is performed in http session, for that purpose I use webbrowser control and webclient. I know it could have been solved in different way, however iam not an expert in vb.net, and also didnt want to spend too much time on it. Anyway it worked, until they had changed something on the server. Let me explain in a few words how that tool works, so it will be easier to understand the problem.
In the first part, I open an URL in the webbrowser control, subsequently I enter xml code in the textarea on that page and click on the submit button. In result of that I get another page with some data on it, namely links to xls files. In the next part I use webclient for downloading those files. What is important for all of these operations I need to use the same http session id.
So, simply by now, i just set headers in webclient - WebClient.Headers.Add("Cookie", WebBrowser1.Document.Cookie.ToString) What have guaranteed to use the same session id by the WebClient. However, after the change made on the server mentioned before, the JSESSIONID value is not available in that string. When I use https analyzer (fiddler), I can see that value there...until moment when I am using WebClient. Of course due to that fact, the webclient won't download files for me, because the session id is not the same.
There is one more thing, what would be useful. When I checked the cookies file on my harddrive, I saw that line starts like #HTTP_ONLY. I think that would cause that problem with jsessionid.
Now, I am coming to my question Do you have any idea, how I would get that JSESSIONID value ? It is sent from webbrowser control, however don't know how to get it.
To .net programming. please can anyone assist me on any .net based simple http server code to implement on my application.

View 4 RepliesI've been trying to get this to work for days now, but I fail I have a very small HTTP Web Server using TCP sockets listening on port 80.

View 1 RepliesI am using Async socket class to handle HTTP data. The OnRecieve event handler looks like this:
Private Sub sck_onDataArrival(ByVal sData() As Byte, ByVal BytesTotal As Integer) Handles sck.onDataArrival
Try
Dim ms As New IO.MemoryStream(sData)
Dim returnImage As Image = Image.FromStream(ms)
Picturebox1.Image = returnImage
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
I realize this will not work because the byte array still contains the header information from the response from the server. How to strip this data without converting the byte array to a string. I need to strip the header response information and just be left with the image data and from there convert that data into a stream so the stream can be loaded into an image and displayed in my picturebox.

I 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.
