IIS URL Rewrite with ColdFusion keeps duplicates string - iis

Question

I have set up a URL rewrite which works fine when I manually set or type in the URL. But when I use a link in the page within a <cfoutput> tag for example, the link duplicates the string.
I'm using ColdFusion 2016 with IIS 10
For example the URL is
www.site.com/results.cfm?lang=1&categoryid=2&budegtid=all&typeid=all&propertyid=316
and I want it outputted like
www.site.com/properties/en/all/all/all/316
it works but what seems to be happing when I set the link using...
<cfoutput> using the query...
<cfif getProps.recordcount>
<cfoutput query = "getProps" startrow="#url.start#" maxrows="#perpage#">
View
</cfoutput>
the result in the link on the page outputs as www.site.com/properties/en/all/all/all/316/properties/en/all/all/all/316
I have web/config set up as
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<directoryBrowse enabled="false" />
<urlCompression doStaticCompression="true" doDynamicCompression="true" />
<rewrite>
<rules>
<rule name="Property list URL rewrite">
<match url="^property/([_0-9a-z-]+)/([_0-9a-z-]+)/budget-range-([_0-9a-z-]+)/([_0-9a-z-]+)/([_0-9a-z-]+)" />
<action type="Rewrite" url="resultsproperty.cfm?lang={R:1}&categoryid={R:2}&budegtid={R:3}&typeid={R:4}&propertyid={R:5}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
<httpErrors errorMode="Detailed" />
</system.webServer>
</configuration>
The ColdFusion cfquery is as follows...
<cfquery name="getProps" datasource="#session.odbcname#">
SELECT *
FROM properties P
INNER JOIN areas A
ON A.area_id = P.property_areaid
INNER JOIN categories C
ON C.category_id = P.property_propcategoryid
INNER JOIN price R
ON R.price_id = P.property_regularity
INNER JOIN types T
ON T.type_id = P.property_proptypeid
WHERE P.property_status != 'Off Market'
<cfif url.ref is not "all">
AND
(
property_ref like <cfqueryparam cfsqltype="cf_sql_varchar" value="%#url.ref#%">
OR property_refid like <cfqueryparam cfsqltype="cf_sql_varchar" value="%#url.ref#%">
OR property_town like <cfqueryparam cfsqltype="cf_sql_varchar" value="%#url.ref#%">
)
</cfif>
ORDER BY P.property_refid
It seems to be pulling in the actual URL first and then adding on the rewrite.
Any help much appreciated.

Answer 1

You need to start the href with a forward slash to indicate it is from root. The href is resolved/interpretted in the browser. Not starting with a forward slash tells the browser that the url is relative to the current path.
If you are at http://example.com/admin/ and have an href logout for example it will be resolved as http://example.com/admin/logout. However if you have an href /logout it will resolve to 'http://example.com/logout.
As your own answer stated, forcing an absolute path works and can be preferred sometimes but sometimes not. Make sure you understand the underlying issue.

Solved! by pre setting the URL root in the coldfusion application file i.e. <cfset request.root = 'http://www.example.com/'> and then reference the #request.root# var within the link, it uses the link correctly and dose not duplicate the url. So this is a cold fusion issue rather than a URL ReWrite issue.
