i have just started learning about httpwebrequest and response to open webpages and get/post info. Anyways i have a working project that connects to a webbrowsewr useing a proxy but this does not workj for httpwebrequest. Im guessing its totally different for httpwebrequest but i have no idea how to work this :/
[Code]....
I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy
[Code] .....
Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
[code].....
View 3 RepliesI'd like to set the proxy for a web request. However, when I say, for example, request.proxy = "x.x.x.x:xxxxx", it gives me the error "String cannot be converted to webproxy". How can I get around this and actually set the proxy?
View 2 RepliesThis is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?
i have a site that i would like to login using httpwebrequest.I have this code and added the correct part to post
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim postData As String = "u_name=" & TextBox1.Text & "&p_word=" & TextBox2.Text & "&login=Login"
Dim tempCookies As New CookieContainer
Dim encoding As New UTF8Encoding
[code].....
If i enter the wrong login info it says bad login, but if i add the correct login info, it does not login, all it does is displays the login page again?

I have a bit of strange behaviour in an asp.net web application that involves the session state being lost.
Process A user logs into the application and the session is set. They then fill out 1 field, and the application then does an AJAX POST to a .asmx web service. Within the web service, I am using a HttpWebRequest to grab data from another server.
This data is then output to the browser.A few more fields are then filled in, and the data is then again Post to the same web service via an AJAX POST.

When 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]
