Question

Firefox mishandling coldfusion session variables when transferring from http to https

Asked by: Eduski

I have an online e-commerce store that I am having problems when sending customers to a https redirect in firefox.  When a customer adds an item to the shopping cart in firefox, and proceeds to checkout, the website redirects them from http to https for credit card processing, etc.  However, it seems to empty the cart when it does so.  You can go back once under https and re-populate the cart, but this is obviously not the ideal solution.  This problem is only with firefox and not with IE or google chrome.  The site in question is http://www.tentandtable.com

Any help is appreciated.

sounds like the developers did not test there CFM in Firefox... and/Or they are not passing the variables from the shopping cart correctly to the https. cant really determine qqith 100% due to not being able to see the CF source :(

i have attached the code that adds the item to the struct (additem.cfm) - i can provide other code if you wish

the application page (application.cfm) is below

<!--- Application Settings --->
<cfapplication name="shoppingCart" sessionmanagement="yes" sessiontimeout="#CreateTimeSpan(0,2,0,0)#">

<!--- Application Variables --->
<cfparam name="application.ds" default="******">

<!--- Monetary Variables --->
<cfparam name="application.taxrate" default="0.0825">

the checkout page (the first one with https) begins with this code:

<cfif CGI.HTTPS EQ 'off'>
     <cflocation url="https://#CGI.HTTP_HOST##CGI.PATH_INFO#">
</cfif>

<!--- additem.cfm --->
<cfif isdefined("attributes.cartpid") and isdefined("attributes.cartqty") and isdefined("attributes.cartprice") and isdefined("attributes.cartshipping") and isdefined("attributes.carttitle")>
		<cfscript>
			if (not(isdefined("session.cart"))) {
				session.cart = structnew();					
				} 
			tempvalue = listtoarray('#attributes.cartpid#,#attributes.cartqty#,#attributes.cartprice#,#attributes.cartshipping#,#attributes.carttitle#');
			if (not(structKeyExists(session.cart, attributes.cartpid))) {
				StructInsert(session.cart,attributes.cartpid,tempvalue);
			} 
			else {
				tempvalue[2]=attributes.cartqty;
				StructUpdate(session.cart,attributes.cartpid,tempvalue);
			}			
		</cfscript>
<cfelse>
</cfif>

i'm not sure why its needed because all that does is output the session variables and run the secure payment. I included the header (the redirect) to the checkout page that has the redirect.  It seems like there's something about firefox that dumps session variables on any redirect, not specifically just to https pages.  The checkout page wouldn't be useful at this point, but here is the cfm code from that page (I'm not being stubborn about providing info just dont want the code printed here)

<cfif CGI.HTTPS EQ 'off'>
     <cflocation url="https://#CGI.HTTP_HOST##CGI.PATH_INFO#">
</cfif> 
<cfset good_promo = 0>
<cfset good_minimum = 0> 
<cfif isdefined("form.cartaction")>
<cfif form.cartaction eq "delete">
<cfloop collection="#session.cart#" item="i">
<cfif isdefined("deleteitem")>
<cfif ListContains(deleteitem,"#i#")>
  <cf_dropItem cartpid="#form["itemproductid" & i]#">
</cfif>
</cfif>
        </cfloop>
    <cfelseif form.cartaction eq "update">
         <cfloop collection="#session.cart#" item="i">
              <cf_addItem cartpid="#form["itemproductid" & i]#" cartqty="#form["itemquantity" & i]#">
         </cfloop>
    </cfif>
</cfif>

NO worries lemmie look at what you have here :)

 

by: EduskiPosted on 2009-11-05 at 11:26:01ID: 25752957

actually after doing some digging the problem seems to be that http://tentandtable.com is handled completely differently than http://www.tentandtable.com.  So I guess what I'm really looking for is some code to redirect everyone so that the domain uses the "www" (since that is the domain the SSL cert is using.  Thanks.

 

by: plusone3055Posted on 2009-11-05 at 11:26:19ID: 25752960

okay im seeing that it DOES  the varaibles correctly.

 there is obviously something missing here. I do not think its "firefox" to blame though :(

two things

put this on each page that needs to be secured

      <cfif cgi.server_port neq "443">
                  <cflocation url="https://www.site.com"
                               addtoken="false">
      </cfif>


the difference between site.com and www.site.com can be eliminated by setting up a host header entry in IIS (or whatever webserver you are using)

here's a tut
http://www.visualwin.com/host-header/

basically you just point site.com and www.site.com to the same IP address

You may still need an additional redirect unless you have a wildcard ssl cert

to do that just

<cfif cgi.server_name eq "site.com">
<cflocation url="http://www.site.com">
</cfif>
