I have a php website with a login page containing username and password fields with the same exact html names. I would like to have a page in my ASP.NET page with a username and a password textbox field that sends the corresponding credentials to the php website using HttpWebRequest. How would I do that and how could I check the response to see if the authentication has been successful?

I am trying to simulate a POST to a form on an external server that does not require any authentication, and capture a sting containing the resulting page. This is what the form looks like:
<FORM METHOD="POST" ACTION="/controller" NAME="GIN">
<INPUT type="hidden" name="JSPName" value="GIN">
Field1:
<INPUT type="text" name="Field1" size="30"
maxlength="60" class="txtNormal" value="">
</FORM>
This is what my code looks like:
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "Field1=VALUE1&JSPName=GIN";
byte[] data = encoding.GetBytes(postData);
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://XXX/controller");
myRequest.Method = "POST";
myRequest.ContentType = "text/html";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
StreamReader reader = new StreamReader(newStream);
string text = reader.ReadToEnd();
MessageBox.Show(text);
newStream.Close();
Currently, the code returns "Stream was not readable".

I am attempting to call a RESTful service using an HttpWebRequest object via POST. I am attempting to pass 1 variable with the Request body which contains a url encoded string. I see the request when it hits the server; however, it shows 2 form variables. The first is Form[null] and the second is my variable.I am attempting to locate the source of this NULL key; however, I cannot. Any ideas on how I may be able to remedy this since it's throwing issues when I attempt to use it with the Nancy web framework for .Net.

var request = WebRequest.Create("http://localhost:8888/RouteName") as HttpWebRequest;
request.Method = "POST";

I have an application that will upload files from my client to a web server using HttpWebRequest (with the function suggested here: [URL]
My problem is that when the file (about 10 mb in size) is being posted the whole application freezes (e.g. "application is not responding" when I try to move the window).
Do I need to put the uploading in a separate thread, or is there any other simple way solve this?
I'm getting the "The underlying connection was closed: The connection was closed unexpectedly." error while trying to POST using the HttpWebRequest class on the production server, on my dev machine it works fine.
I originally tried using the WebClient class but I switched to the HttpWebRequest to try some of the suggestions I found while researching the issue (such as setting KeepAlive to false, PreAuthenticate true and ProtocolVersion to 1.0).
Since it's only happening on the production server, i'm guessing that it might have something to do with IIS.
Here's my code

If set the Target Framework (I used a new project for testing) to 2.0 (I didn't test every version of the framework) it works. I'm guessing that .net handles the security differently in .net 4.0.

View 4 RepliesI've searched everywhere for this but I'm unable to solve it by myself. I'm try to webscrape a website using HttpWebRequest. I'm able to login successfuly and to browse through the different pages to obtain all cookies and viewstates as needed. Fiddler supports my claim as I compared all the information. There is one page which I'm unable to load - This page has a certain AJAX loader which prevents me from getting to the page I need. Apperntly page
(1) makes some sort of calculations and when finished transfers to page
(2) using AJAX. If I try to scrape page (2) directly I get an empty page, without the calculations which I need to scrape.
When I send a request to page (1) it just returns the error posted in the subject: 179|error|500|The page is performing an async postback but the ScriptManager.SupportsPartialRendering property is set to false. Ensure that the property is set to true during an async postback.
Here is my code to post the file. I use asp fileupload control to get the file stream.

requestToSender.Method = "POST";

In the page load of CrossPage.aspx i have the following code
NameValueCollection postPageCollection = Request.Form;
foreach (string name in postPageCollection.AllKeys)
{
Response.Write(name + " " + postPageCollection[name]);
}
HttpFileCollection postCollection = Request.Files;
foreach (string name in postCollection.AllKeys)

aFile.SaveAs(Server.MapPath(".") + "/" + Path.GetFileName(aFile.FileName));
}
string strxml = "sample";
Response.Clear();
Response.Write(strxml);
I don't get the file in Request.Files. The byte array is created. What was wrong with my HttpWebRequest?
I want to have a PHP login form on my website. When the user enters a username and password and clicks submit, they should be directed to a remote website logged in (therefore skipping the login form on the remote site).
As mentioned in the title, the remote site is built using ASP.NET.
I've tried to search for a solution this but really not finding.
AJAX is under the same origin policy. Is there a clean way to use ajax to post data to a remote .aspx page and get response ?

In IE the website keeps asking several times for my credentials per webpage. In Firefox it works correctly.
Platform: ASP.NET 4.0, VS 2010My scenario is thishave the credentials of an external websiteI do a couple of GET/POST to scrape some data off of it
Depending on something that I find, I want to give my user a hyperlink that, when clicked, takes him 3 levels deep into the target website beyond the login pageOf course, I could just provide a URL to the top level on the target site, and he would click through to get there. But is there a way, via ASP.NET, that I can programmatically login and then open the page on a separate window/tab?
1) I have an ASP.NET website which is the main entry point in the application.This website uses Forms authentication, which validates credentials (username/password) against a database. 2) Once logged on the website, the user is displayed a page containing several links which point to a Sharepoint 2007 application, where authentication is managed by an Active Directory. 3) Every user in the Active Directory is duplicated in the database managing the ASP.NET website authentication.

I'm working on an ASP.NET project for the first time in about three years; in the meantime I've been working with Python/Django, PHP and Obj-C. Anyways, picked it right back up... except something that is totally killing me right now, and I have a feeling it must be staring me in the face:
I'm trying to bind to an LDAP server, for the purpose of authenticating users. The way it works here is, you bind on your own credentials, use that to find the Distinguished Name of the user you're authenticating, then you bind again on their DN and their password. If the bind is successful, the password was correct and the user can be authenticated.
Here's the problem - the first bind (on the fixed credentials, the ones with the ability to search for users and their subtrees) works fine. The search works fine. The second bind fails, no matter what, with the LDAP error INVALID_CREDENTIALS. This happens even when completely valid credentials are supplied.
Here's the code, with the usernames and passwords redacted, of course...
