[mapserver-dev] WMS and cookies

[Lime, Steve D (DNR)]

Perhaps this could be controlled by env vars? MS_OGC_IGNORE_COOKIES, MS_CGI_IGNORE_COOKIES and perhaps even an order one (e.g. MS_PARAMS_BEFORE_COOKIES) one. These would be set in the webserver configuration and processed within cgiutil.c. Since a runtime option isn't possible this would be better than a compile-time one... Just thinking out loud.

Hi Assefa,

my patch just disables the cookies since I did not need that functionality, so it is too blunt.

See also Steve's reaction here:

Best regards,
Bart

Maybe It should be the other way around; It would change the current behavior but  I could not find in MapServer  docs explaining the current behavior so I tend to believe that It is not used consciously by a lot of users.
