[TYPO3-dev] Is config key 'cookieDomain' worth a patch?

[Steffen Kamper]

Hi Xavier,

the problem with multidomain is not solved with setting cookie to 
".domain.ltd" - it won't work if subdoamins are in different A-record.

I researched for it because of handling cookies on support.typo3.com and 
it is unsolvable for the different subdomains, cookies are not valid for.

i see a possibility with a CNAME record, have a look at this article:
