Trouble removing cookiesI am having trouble removing cookies that I created with my site. Here is
the code I am using to try and remove them: If Not Request.Cookies("username") Is Nothing Then Response.Cookies.Remove("username") If Not Request.Cookies("password") Is Nothing Then Response.Cookies.Remove("password") Is there something I am missing here? Even after I do a Session.Abandon() the cookies still seem to be there. Is there another step that is necessary? Thanks. Nathan,
Instead of removing the cookies (I believe that just removes them from the server memory and not the client) you should overwrite them on the client. If Not Request.Cookies("username") Is Nothing Then Response.Cookies("username") = "" End If Oh, and even an empty cookie may not be equal to "Nothing" because it is a string you may need to test for "" instead. -- Show quoteHide quoteSincerely, S.

I'm not certain about that myself... It really may just be the object they chose to hook up cookies with. It looks like the object is ultimately inheriting from something similar to arraylist (if it isn't arraylist itself I didn't bother to check). It may not be that they intended Remove to even be used. It may just have come along for the ride via inheritance. -- Show quoteHide quoteSincerely, S. Justin Gengo, MCP Web Developer / Programmer www.aboutfortunate.com "Out of chaos comes order."
