Getting and Setting cookies

I was recently having a lot of trouble trying to set and read a cookie in  I discovered that my big issue was not correctly using the Request and Response objects.  The Request object is only used for retrieving a cookie, while the Response object is only used for creating a cookie.

Another little anomaly I found.  Apparently the client doesn't send the experation date of a cookie when it sends the cookie to the server.  So, in when retrieving a cooky the experation date will always be MinDate even if the date is set correctly.

    HttpRequest oRequest = System.Web.HttpContext.Current.Request;
    HttpResponse oResponse = System.Web.HttpContext.Current.Response;

      HttpCookie oCookie = oRequest.Cookies[ConfigurationManager.AppSettings["anonUserCookie"]];
      if (oCookie == null) oCookie = new HttpCookie(ConfigurationManager.AppSettings["anonUserCookie"], Guid.NewGuid().ToString());
      oCookie.Expires = DateTime.UtcNow.AddMonths(1);

IE7 div centering with margin auto

I've been having some problems getting a div to center on a webpage.  All the websites I have visited said the fix was easy and gave me various forms of this as a solution:

<div style="text-align:center;">
<div style="text-align:left;">
Content goes here.

However, no matter what I put in my stylesheet I couldn't get it to work.  Turns out this fix has to be applied inline.  Putting it in a stylesheet doesn't work.  Once I got that figured out and grumbled for a bit everything worked great.
