Description

I have a server that sets a bunch of empty cookies:

2003/03/06 16:28:52:055 PST [DEBUG] wire - -<< "Set-Cookie: list%2ESince=;
path=/[\r][\n]"
2003/03/06 16:28:52:055 PST [DEBUG] wire - -<< "Set-Cookie: search%2EPhoneSDA=;
path=/[\r][\n]"

On subsequent requests, httpclient attaches these cookies thusly:

2003/03/06 16:28:55:480 PST [DEBUG] wire - ->> "Cookie: $Version=0; list%
2ESince=null; $Path=/[\r][\n]"
2003/03/06 16:28:55:480 PST [DEBUG] wire - ->> "Cookie: $Version=0; search%
2EPhoneSDA=null; $Path=/[\r][\n]"

I'm not sure how to read this portion of wirelog, but seems that actual
values containing the string "null" are being sent as part of the request.
In the response to my request, the server now echos cookies with "null"
values back to me.

2003/03/06 16:28:55:660 PST [DEBUG] wire - -<< "Set-Cookie: search%
2EPhoneSDA=null; path=/[\r][\n]"
2003/03/06 16:28:55:660 PST [DEBUG] wire - -<< "Set-Cookie: list%2ESince=null;
path=/[\r][\n]"

This isn't good. Basically, the list.Since= cookie is being
converted to list.Since=null. This causes the server's script to
crash:

<p>Microsoft VBScript runtime </font> <font face="Arial"
size=2>error '800a000d'</font>
<p>
<font face="Arial" size=2>Type mismatch: 'CINT'</font>
<p>
<font face="Arial" size=2>/listCust.asp</font><font face="Arial" size=2>, line
283</font>

I guess the script tries to assign the string "null" to an integer, and
dies.
