I maintain a well-trafficked site on CF9 that has occasional memory problems
that ultimately requires restarts. I am fairly certain the cause of my
problems is related to "bot" hits and the server's memory they take up. I am
attempting to set low sessionTimeouts to all bots to remedy this situation.
I've listed a few code samples below I found while researching a solution.
Is there a "best practice" as to handle this? Any additional code samples
would be welcome.
Thanks, Che
Method #1
<cfif structKeyExists(cookie, "CFID")>
<cfset this.sessionTimeout = createTimeSpan(0,0,10,0)>
<cfelse>
<cfset this.sessionTimeout = createTimeSpan(0,0,0,2)>
</cfif>
Method #3
<cfif isBoolean(URLSessionFormat("true"))>
<cfset this.sessionTimeout = createTimeSpan(0,0,10,0)>
<cfelse>
<cfset this.sessionTimeout = createTimeSpan(0,0,0,2)>
</cfif>
Method #3
<cfset this.sessionTimeout = createTimeSpan(0,0,10,0)>
<cfif len(cgi.http_user_agent) gt 0>
