Here is a complete discussion on the character set of cookie name (for python development): http://bugs.python.org/issue2193

I think *drakma *should follow python's work.

In file "util.lisp" of *drakma*, function *split-set-cookie-string* splits cookie string using function* is-valid-cookiename-char* which comes from * chunga*. But function* is-valid-cookiename-char *just follow *RFC2616* which rules that chars of cookie name are legal when they are in* token set *( see bellow)*. *

token = 1*<any CHAR except CTLs or separators> separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT

* *That is not practical!*

*In python, letters, digits and "!#$%&'*+-.^_`|~:"* http://hg.python.org/cpython/rev/8cae3ee7f691#l1.15 *are legal in Cookie name.
