Hello

One of my clients use period(.) as cookie name start.  
(ex Set-Cookie: .blabla=abcd)

Is it possible to use period(.) in a cookie name?

If possible, how can I use $cookie\_COOKIE variable ?

Best Regards

I don’t know if things have improved since

I think you can access those in embedded Lua or Perl.

Just vanilla map module should do the trick (if/set will do too,  
but map is better).

The link already provided in this thread contains if/set based  
solution. Map-based solution will be similar (it’s now possible  
as regexp support was added to map module).
