I have an Application.cfc with the following settings:
<cfset THIS.Name = "Test01" />
<cfset THIS.ApplicationTimeout = CreateTimeSpan(1,0,0,0) />
<cfset THIS.sessionTimeout = CreateTimeSpan(1,0,0,0) />
<cfset THIS.clientManagement = false />
<cfset THIS.SessionManagement = true />
<cfset THIS.SetClientCookies = false />
<cfset THIS.setDomainCookies = false />
And I attempted to send the following cookies:
<cfcookie name="CFID" value="#session.CFID#" domain=".test01.domain.net" path="/" expires="never">
<cfcookie name="CFTOKEN" value="#session.CFTOKEN#" domain=".test01.domain.net" path="/" expires="never">
However, what gets sent to the browser is:
Set-Cookie: CFID=6389; Domain=.domain.net; Expires=Fri, 12-Jun-2043 22:14:17 GMT; Path=/; HttpOnly:
Set-Cookie: CFTOKEN=783fa62afecfd571%2DB1069303%2D3048%2D3344%2DAA97ADAF73598FA6; Domain=.domain.net; Expires=Fri, 12-Jun-2043 22:14:17 GMT; Path=/; HttpOnly
No matter what values I put in domain or path, it always sends those same headers. If I try to use cfheader it simply sends nothing. The only time I can get it to send cookie headers without a domain value is by setting SetClientCookies to true:
Set-Cookie: CFID=6391; Expires=Fri, 12-Jun-2043 22:21:38 GMT; Path=/; HttpOnly
However I can no longer get rid of the cookies by using StructDelete nor CFCookie with the attributes expires now (in fact it creates a second set of cookies).
My main goal is to simply send CFID and CFTOKEN cookies without a domain (or at the very least without a leading period, e.g. test01.domain.net)
Thanks to Henry I took a look at using cfheaders again by having a closer look at the headers sent by CF10 when using <cfset this.SetClientCookies = true>. CF10 omitted the domain value in the header sent to the browser so I copied the header CF10 sent and put it in a cfheader:
<cfheader name="Set-Cookie" value="CFID=#session.CFID#; Expires=#GetHttpTimeString(DateAdd("yyyy", 40, Now()))#; Path=/">
<cfheader name="Set-Cookie" value="CFToken=#session.CFToken#; Expires=#GetHttpTimeString(DateAdd("yyyy", 40, Now()))#; Path=/">
Lo' and behold the browser received the cookie without the domain value having a leading period. I also managed to expire those cookies with the following code:
<cfheader name="Set-Cookie" value="CFID=#session.CFID#; Expires=#GetHttpTimeString(Now()-1)#; Path=/">
<cfheader name="Set-Cookie" value="CFToken=#session.CFToken#; Expires=#GetHttpTimeString(Now()-1)#; Path=/">
<cfset StructClear(session)>
<cflocation url="/" addtoken="no">
The only quirk it seems that while testing out that block of code using a url variable in Chrome, Chrome would send out a HTTP request when simply typing ?ResetSen in the address bar causing a second request when I hit enter. This would lead to oddities such as skipping a CFID (7249 -> 7251) or just sending out both sets of cookies (expire: indefinite and expires: now).
Nevermind, the real issue seems to be the expiry time not elapsing (two requests in the same second), I changed that portion to #GetHttpTimeString(Now()-1)# which is one day in the past and that seems to holding up.
Originally this:
<cfheader name="Set-Cookie" value="CFID=#session.CFID#; Domain=test01.domain.net;Expires=Sat, 04-Jul-2043 13:24:38 GMT; Path=/">
<cfheader name="Set-Cookie" value="CFToken=#session.CFToken#; Expires=Sat, 04-Jul-2043 13:24:38 GMT; Path=/">
Sent this:
Set-Cookie: CFID=7191; Domain=test01.domain.net; Expires=Sat, 04-Jul-2043 13:24:38 GMT; Path=/
Set-Cookie: CFToken=33b984d7a56f6356-0B97F3CF-3048-3344-AABF2B698F4B8B02; Domain=test01.domain.net; Expires=Sat, 04-Jul-2043 13:24:38 GMT; Path=/
Which the browser receives as .test01.domain.net which is what I wanted to avoid.
Yes, this does seem like <cfcookie> is doing too much by stripping any domain value to .domain.tld. See: why doesn't cfcookie allow setting domain= to a subdomain for CFID/CFTOKEN?
I'm not sure why, but the workaround would be using <cfheader>
In order to modify session cookies in your code you should add the following in your Application.cfc pseudo-constructor:
<cfset this.sessioncookie.disableupdate = false>
This can also be controlled at the server level under the 'Memory variables' section in the CF administrator.
