Webmaster Forum / ColdFusion / Advanced Techniques / March 2008How to strip #CGI.HTTP_REFERER# after the ? params?
I am trying to store the #CGI.HTTP_REFERER# address into my database, which works, BUT, I don't want any characters after and including the ? in my url for example, if I have http://www.scooby.com/index.cfm?popo=yes&ID=22 I only want to store http://www.scooby.com/index.cfm How can I strip that stuff after the ? before storing it? Figured it out.. <cfset prefix = "http://"> <cfset full_path = "#prefix#" & "#CGI.SERVER_NAME#" & "#CGI.SCRIPT_NAME#"> [i]Figured it out.. <cfset prefix = "http://"> <cfset full_path = "#prefix#" & "#CGI.SERVER_NAME#" & "#CGI.SCRIPT_NAME#"> [/i] Those are two different things. CGI.SERVER_NAME and CGI.SCRIPT_NAME refer to the current page. CGI.HTTP_REFERER is the previous referring page. You can use list functions to extract the first part of the HTTP_REFERER string listFirst(CGI.HTTP_REFERER, "?") <cfset myNewLink = ReplaceNoCase(cgi.http_referer,"?"&cgi.query_string,"")> |
