title: What is AspxAutoDetectCookieSupport
body: <p>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. </p>
  
  <p>The parameter 'AspxAutoDetectCookieSupport' goes away when I visit the URL again. What does 'AspxAutoDetectCookieSupport=1' mean? </p>
