[TYPO3-english] FE login error behind CDN

[Daniel Tâche]

Hello,

I've got a strange problem with the FE Login.
I've got a website which is behind a CDN, the main website is 
cdnmyweb.net (which is only for us to access typo3) and it is deploy by 
CDN for public acces to myweb.com. Everything is ok except the FE login, 
when I try to login, the website is redirected to cdnmyweb.net ! I've 
tried with different login and it's still the same.

Anyone has an idea ?

Many thanks for your help
