Cookie parsing fails for admittelly bad cookies

[ckonstanski]

I am writing against the Infoblox REST API. The moment I try to use a cookie-jar I get the following error:

end of file on #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}> [Condition of type END-OF-FILE] Backtrace: 0: (READ-BYTE #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}> T NIL) 1: (CHUNGA:READ-CHAR* #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}> T NIL) 2: (CHUNGA::READ-QUOTED-STRING #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}>) 3: (CHUNGA::READ-COOKIE-VALUE #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}> :SEPARATORS ";") 4: (CHUNGA:READ-NAME-VALUE-PAIR #<FLEXI-STREAMS::LIST-INPUT-STREAM {1004BF43C3}> :VALUE-REQUIRED-P T :COOKIE-SYNTAX T) 5: (DRAKMA::PARSE-SET-COOKIE "ibapauth="client=API,group=VCP-Meter,ctime=1538755942,timeout=7200,mtime=1538755942,ip=10.134.10.30,auth=LOCAL,user=openbook,Rw+KK2u56eG1OP13xpSkhnQgaQteIjrVJIs"; httponly.. 6: (DRAKMA::GET-COOKIES ((:DATE .

It breaks because of this cookie:

set-cookie: ibapauth="client=API,group=VCP-Meter,ctime=1538755825,timeout=7200,mtime=1538755825,ip=10.134.10.30,auth=LOCAL,user=openbook,xbGCCBttvLHdRCahtYaAZVsixnZHaY57zMM"; httponly; Path=/; secure

Here's the output stream which shows where the breakage occurs. It looks like the comma is the point of failure, but the real issue is that the cookie parser doesn't know how to treat a quoted string as a single atomic value.
