Bug 247037 – Safari strips whitespace around comma when setting with document.cookie

• Status: NEW
• Component: WebCore Misc.

[April King]

Extremely bizarre bug and I'm hard pressed to think of what would cause it but running this code:

> document.cookie="foo=hello , world"
< "foo=hello , world"
> document.cookie
< "foo=hello,world"

Shows that setting a cookie to "hello , world" causes it to be saved as "hello,world".

Note that using characters besides commas seem to not have this issue:

> document.cookie="foo=hello $ world"
< "foo=hello $ world"
> document.cookie
< "foo=hello $ world"

One theory is that the cookie value is parsed by a function that treats commas as in HTTP, separating multiple values.

In NetworkStorageSessionCocoa.mm:

    NSHTTPCookie *initialCookie = [NSHTTPCookie _cookieForSetCookieString:cookieString forURL:cookieURL partition:nil];
