On our Tridion 2013 SP1 environment we get the following error message regularly. What can be the issue here?
It occurs when browsing through the CMS.
The issue dissappears when clearing cookies. I don't think there is something wrong with Tridion itself.
I will investigate further.
Following two cookies are responsible for the error:
Those cookies are set on another website with the same domain. Tridion is on a subdomain of that website.
When those two cookies are set, all requests in Tridion gresult in a 400 or a 500 error. When I remove OR empty the cookie values, the issue is fixed.
An idea came into my mind. I created a test cookie with a comma in it and... Tridion gave the same errors:
So it looks like Tridion can't handle cookies with comma's and braces. Is there a fix for?
