isdefined("cookie.ASP.NET_SessionId") (returns false)
#ASP.NET_SessionId# (returns an exception, because the scope ASP doesn't
exist. Also tried with cookie.ASP.Net_SessionId)
I used this workaround:
<CFSET start = find("ASP.NET_SessionId=",http_cookie,1) + 18>
<cfif start gt 0>
<CFSET end = find(";",http_cookie,start)>
<cfif end lt 0>
<cfset aspsession = mid(http_cookie,start,999)>
<cfelse>
<cfset aspsession = mid(http_cookie,start,end-start)>
</cfif>
</cfif>
(Why do I care about ASP.NET sessions? Because I implemented a dual-login
system. User logs in to ASP and is auto-logged into the CFML site.)
