Strange behavior with HttpCookieCollection

[adlaird]

Hi,

I created a simple webform, put a test button on it and implemented a
click handler that looks like so:

private void btnTest_Click(object sender, System.EventArgs e)
{
HttpCookieCollection oCookReq =
HttpContext.Current.Request.Cookies;
HttpCookieCollection oCookResp =
HttpContext.Current.Response.Cookies;

int n1 = oCookReq.Count;
int n2 = oCookResp.Count;
bool bIsNull = (oCookResp["someCookieName"] == null);
int n3 = oCookReq.Count;
int n4 = oCookResp.Count;

Response.Write(string.Format("Before: Request = {0}, Response
= {1}<br>", n1, n2));
Response.Write(string.Format("After: Request = {0}, Response
= {1}<br>", n3, n4));
}
When I click the button the test output on the page is:

Before: Request = 1, Response = 0
After: Request = 2, Response = 1

Can anyone explain why the mere act of looking for a cookie in the
response collection would cause one to get added to both the response
and request collections? I tried the test again using a new
HttpCookieCollection (i.e. not one from the current context) and do
not get this behavior. Clues?

Thanks much...
