WebKit does not support the Set-Cookie header field correctly as specified in RFC 2109.
Consider the following Set-Cookie response header field:
Set-Cookie: foo=bar; Version=1; Max-Age=0
Though the Version attribute is set and the Max-Age attribute value is zero (which means the cookie should be discarded immediately) this response header field is treated as a normal "Netscape Cookie" Set-Cookie header field.
Does this work in other browsers?
In Opera 9.22 this works correctly.
Confirmed as an enhancement request.
This issue is in a lower level system framework, not in WebKit. Closing as INVALID per our process; this will continue to be tracked internally by Apple.
