Recently, I noticed about having AspxAutoDetectCookieSupport=1 in the URL when I clear browser cookies. Upon doing a short research, I found out that it is result of cookieless attribute set to "AutoDetetct" in web.config.
The parameter 'AspxAutoDetectCookieSupport' goes away when I visit the URL again. What does 'AspxAutoDetectCookieSupport=1' mean?
