Cookie issue, fix was flushdns? RRS feed

  • General discussion

  • I wanted to throw this question out there hoping someone would have some details. 

    I recently did ESPN Fantasy Football draft with friends. Everyone in the group but one guy had logged into their account for the first time. The guy that had logged in before, got a popup that said "Cookies must be enabled to connect to this site", something like that. He was connecting via "Chrome". We were on our buddies wifi and the guy who couldn't connect usually connects from his home. I checked the settings and cookies were enabled. Essentially I ended up doing ipconfig /flushdns, and behold it fixed it. My thought was that the issue had to do with connectivity from the new network. 

    Questions: 
    Does flushdns modify the session cookie/cookies or have anything to do with the cookies? 
    What all is stored in the cookies? 
    Why would flushdns change anything? 

    Anyone know of any good resources on what is stored or any good diagrams? Any thoughts would be appreciated.

    Cheers.

    Not unless the Cookies were referencing explicit IP addresses but I think that would be more likely to involve the client's address not the host's.

    Why would flushdns change anything? 

    In fact, in that case, where a successful connection had already been made, it might not, unless you also closed all instances of iexplore.exe to prevent IE from trying to reuse its cached lookup.

    FWIW the only thing that I use it for is to change the timing and the diagnostics for the initial request.  E.g.  ipconfig /displaydns  is a lot easier to read and more relevant then.

    In addition to Robert's explaination:

    A cookie is a small bit of text that accompanies requests and pages as they go between the Web server and browser. The cookie contains information the Web application can read whenever the user visits the site.

  • If the flushdns only caused the computer to do a fresh lookup which I know that much about it, I wonder what purpose the cookie would have in conjunction with connectivity, if the user still had to reconnect to a site if they move location.

    I'm only curious about this because I have been through training where the computer presented a cookie to the site and it was rejected because the site did not want to persist on the cookie.  I'm possibly going on and on about something that is not a big deal but just would like to know why the cookie would even affect connectivity at all if it did.

    Thanks to all for the comments.
