How to make an HTTP Post request from inside ASP .Net Page and also trasfer the page

Hi,

I am stuck in a situation where I have to make a http web request to another website's web page(asp) from withing the ASP .Net application and also pass the control to that ASP page.

Means I want use HttpWebRequest classes and also want to do server.trasfer. but the final page should be able to get the values passed by using Request.form("values") .

Please guide me.

Thanks

Many thanks for above code.

Using the above code, the receiving page will not able to use request.form("posted values from sending page") .

I want to create a http post and also redirect to the page....so that the receiving page can receive those values.

I cannot use get method since the data will be visible in the URL and is sensitive.

Please help !

Once again thanks

Adding postData is easy.. look at the URLs

Dim postData

postData = "field1=" & request.form("field1")
postData = postData & "&field2=" & request.form("field2")

Call objHTTP.open("POST", url, False)
Call objHTTP.send "Content-Type", "application/x-www-form-urlencoded"
Call objHTTP.send postData

How is the data visible?

Thanks for your immediate response.

I am trying to run this....
What is your opinion?

objRequest = CType(WebRequest.Create("http://xyz/dmz/abc.asp"), HttpWebRequest)
objRequest.Method = "POST"
objRequest.ContentType = "application/x-www-form-urlencoded"
objRequest.MaximumAutomaticRedirections = 1
objRequest.AllowAutoRedirect = True

'create message body
encoding = New UTF8Encoding()
arrRequest = encoding.GetBytes(UrlString.ToString)
objRequest.ContentLength = arrRequest.Length
strmRequest = objRequest.GetRequestStream()
strmRequest.Write(arrRequest, 0, arrRequest.Length)
strmRequest.Close()

Sorry missed the point..... The above request is not transferring the web page to asp page.

cheekycj

Where is the redirect?

Many thanks CJ you are the only hope for me to come out of this deep ocean of problem somehow I am stuck and feel like lost.

if I will do the redirect using response.redirect I lose all the values of the HTTP Post or should I do the redirect after execute the above code... I think that will be another request and I know I will lose all the POST values.

Please advice how should achieve the above goal..... I have to pass values from a .aspx page to a .asp page.

Once again thanks...

Many thanks.

After all those tries I have reverted back in using URL based get method.

Thanks for your efforts.
