David,
This is how I do it (my UDF)... Root path is the root directory from the
server standpoint (easy to determine if calculated in a given file) and the
CGI object:
The method CleanWebPath() merely makes sure we have "/" as oppossed to "\"
in the paths.
<cffunction name="CalculateSiteUrl" access="private" returntype="string"
output="no"
hint="Calculates the website's root url based on the root folder and the
current url.">
<!--- Define arguments. --->
<cfargument name="RootPath" type="string" required="yes" />
<cfargument name="CGI" type="struct" required="yes" />
<cfscript>
// Define the local scope.
var LOCAL = StructNew();
// Get the http string and server address.
if (NOT CompareNoCase(ARGUMENTS.CGI.https, "On")){
LOCAL.HttpPrefix = CleanWebPath("https://"; & ARGUMENTS.CGI.http_host
& "/");
} else {
LOCAL.HttpPrefix = CleanWebPath("http://"; & ARGUMENTS.CGI.http_host
& "/");
}
// Convert both the root path and the script name to web paths.
LOCAL.RootPath = CleanWebPath(LCase(ARGUMENTS.RootPath));
LOCAL.WebPath =
CleanWebPath(LCase(GetDirectoryFromPath(ARGUMENTS.CGI.script_name)));
// Remove the beginning slash of the web root if there is one.
LOCAL.WebPath = REReplace(LOCAL.WebPath, "^[\\/]{1}", "", "ONE");
// Check to see if we have a web path. If we do not, then we are
already in the
// root directory which means that we can just return the server name.
if (Len(LOCAL.WebPath)){
// Start deleting the web path characters until the entire web path
is at the end
// of the root path (or we have run out of characters).
while(
(Len(LOCAL.WebPath)) AND
(Compare(Right(LOCAL.RootPath, Len(LOCAL.WebPath)),
LOCAL.WebPath))
){
// Check to see if we have a character to delete.
if (Len(LOCAL.WebPath) GT 1){
// Delete the right most character of the web path.
LOCAL.WebPath = Left(LOCAL.WebPath, (Len(LOCAL.WebPath) - 1));
} else {
// We are about to run out of characters, so just set to empty.
LOCAL.WebPath = "";
}
}
// At this point, we either have no more web path, or the path that
we do
// have should be the webroot of the site (ending with the
appropriate slash).
// In either case, just return the http prefix with the remainin
webroot.
return(LOCAL.HttpPrefix & LOCAL.WebPath);
} else {
// Just return the http prefix.
return(LOCAL.HttpPrefix);
}
</cfscript>
</cffunction>

Subject: [CFCDev] GetDirectoryFromPath()
<cfset APPLICATION.siteURL =
replace(GetDirectoryFromPath("http://"&cgi.server_name&;
cgi.path_info),"\","")>
I see this used alot to determine the site URl. However, it doesn't seem to
work all the time. I notice that if you enter anywhere but the main page on
the first request, then this variable will be set to that page.
Is there a better way to determine the site_url no matter what page in the
app you hit first?
