Inserting Cookies into HttpWebRequests

I've spent half a day on this with no success, so I'm hoping someone
can point out what I'm doing wrong.

I have an ASP.NET Server-side component that I've created, and as part
of its Render function, it requests another webpage (which the user
defines) through an HttpWebRequest object.
This page that is being called requires the cookie objects that are
sent to the page hosting the control. So, as shown in the code below,
I'm looping through the host page's HttpContext object's Cookies (which
are instances of System.Web.Http Cookie) and creating instances of
System.Net.Cook ie. These are then added to a
System.Net.Cook ieCollection, which is tied to the HttpWebRequest object.

Here's the code, I'll explain the problem below it.

HttpWebRequest request =
(HttpWebRequest )WebRequest.Cre ate(sTreePage+" ?load=initial") ;
CookieContainer cookies = new CookieContainer ();
for (int i = 0; i < context.Request .Cookies.Count; i++) {
System.Web.Http Cookie hc = context.Request .Cookies[i];
Cookie c = new Cookie(hc.Name, hc.Value);
c.Domain = "localhost" ;
request.CookieC ontainer = cookies;
HttpWebResponse response = (HttpWebRespons e)request.GetRe sponse();

The code above runs fine, until it gets to the final line, where it
(eventually) times out on the GetResponse().
If I leave out the cookies section (ie. just use the first and last
lines) it works fine. But I need the data the cookies hold on the next
page. And, If other people are using the control, I'd like this layer
to be as transparent as possible.

The main annoyance is that there's two different, incompatible (afaik)
Cookie classes, so I can't just copy them between collections.

I've tried CookieContainer .Add(Uri, Cookie), using the RequestUri from
the HttpWebRequest object - which only works if the cookie domain is
".local" - but its no different. I have to set the domain, else it
throws an exception. And yes, I'm running this all off my local machine.

So how is what I'm doing wrong? Why isn't this working?
Any suggestions or comments are extremely welcome.

I am in the process of running my site through WC3 validation. I assume the validator at www.w3c.org cant accept cookies and so PHP is attaching &PHPSESSID=lasklijasj09jsad (or similar) to my URLS. The problem is the leading character is a literal & rather than a &amp; and this is stopping the validator telling me my pages are valid. What do I do here --

Hi all, Anyone know of any special issues with storing cookies with ASP? I'm trying this with two browsers: One is IE 6.0 with cookies set to 'prompt'.

My problem is that the cookies dont seem to be being written with my ASP. I dont get the prompt to store...

Hi... I've come across some weird bug with Response.Cookies. Or maybe it will be called "by design" but for the life of me I can't figure out what purpose it would serve. If you're setting a cookie (say Response.Cookies ("TEST")) and you have a query string variable &test=x or &Test=x and you get Request.QueryString to parse the query string, the cookie that gets dropped matches the case of the query string, not what your code says. ...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
