You can set a special variable in the included file and check for it
before including it anywhere to ensure it only gets loaded once no
matter how many times you call it. In the include:
<cfset someSpecialVariable = 1>
When you include that file:
<cfif not isDefined("someSpecialVariable")>
<cfinclude template="myInclude.cfm">
</cfif>

That depends on the type of data being passed in. For general text
fields a trim() will do the job, and you can combine that with other
functions to ensure it won't cause a SQL truncation error. For integer
values I generally use:
<cfset url.someID = min(abs(val(trim(url.someID))), 2147483647)>
This guarantees a positive integer to prevent errors in a variety of places.
