I apologize for posting this again, but alas, my first post didn't get any replies
(which surprises me from this group). Can anyone possibly help me?
I've run this past our internal CFTalk like list and nobody has come up with an answer
either. Now I realize that cfcookie is client side code and everyone tells me that I
shouldn't be experiencing the problem that I am... Yet I AM having this problem and
many others have verified that this chunk of code is indeed forcing the page to
refresh, yet nobody can explain why.
My thanks to all for supporting the people on this list (I've been lurking on and off
for a year or two).

Subject: cfcookie and browser back button - causes page refresh - help?
Hi y'all
I have a new issue that has me stumped. Maybe if i talk it out, someone will know the
answer.
I have a CFMX include (tho the same thing probably happens in a CF5 environment tho i
haven't gone back and tested it) that i'm using to create a popcorn trail at the top
of all the pages in my site. We opted to use cookies to do this (yes, there are a
million other ways)... and i've recently discovered this is causing a problem.
There is something in the code shown at the bottom of this note that is causing my
problem. If I leave the code uncommented, the code executes and cookies are properly
created -- yet if i use the browser back key on any page, the previous page (which
also executes the same code) re-executes - even tho the traditional back button action
is to just display the page as it was. The real problem occurs when the previous page
was a form - the refresh forces all of the user entered data to be lost and I don't
want that to happen!
If I comment out the code, everything works ok (tho the popcorn trail obviously isn't
created) - but the back button in the browser does NOT cause the page to refresh
automatically.
Does anyone know WHY this code would cause the browser to force a page refresh in both
IE5.5 and NS 4.73?????? (Stuck there due to work requirements - can't go to newer
browsers - sorry I can't share a link with the group - 'tiz inside a firewall)
Here's the code that seems to be the problem:
cfif get_page.menuLevel eq 1>
<!--- If cookie 1 already exists - delete and set new --->
<cfif isdefined("cookie."&#site.siteName#&"cookie1")>
<!--- If the cookie1 is already defined, delete and create new --->
<!--- Delete Old! --->
<cfcookie name="#site.siteName#cookie1"
value="<a href='index.cfm?#cgi.QUERY_STRING#'><font
color='ffffff'>#get_page.menuTitle#</font></a>"
expires="NOW">
<!--- Create New! --->
<cfcookie name="#site.siteName#cookie1"
value="<a href='index.cfm?#cgi.QUERY_STRING#'><font
color='ffffff'>#get_page.menuTitle#</font></a>"
expires="1">
<!--- If a new cookie1 is being set, and cookie2 exists, delete cookie2 --->
<cfif isdefined("cookie."&#site.siteName#&"cookie2")>
<!--- Delte Old! --->
<cfcookie name="#site.siteName#cookie2"
value="<a href='index.cfm?#cgi.QUERY_STRING#'><font
color='ffffff'>#get_page.menuTitle#</font></a>"
expires="NOW">
</cfif>
<!--- If cookie1 does not exist - create --->
<cfelse>
<!--- Set the cookie! --->
<cfcookie name="#site.siteName#cookie1"
value="<a href='index.cfm?#cgi.QUERY_STRING#'><font
color='ffffff'>#get_page.menuTitle#</font></a>"
expires="1">
</cfif>
<cfelse>
<cfif isDefined("URL.debug")> not level 1<br></cfif>
</cfif>
