Hi Friends,

I am new to salesforce. My requirement is that we are using our company LDAP authentication. Upon successful authentication it should redirect the user to salesforce free site url but before it hits free site URL I wanted to check in  the header URL to grab the HOST so that I can determine from where the request is coming from and if i found the reqest  is coming from valid HOST then i will let the user to see our free site page otherwise will show him the error page.

LDAP-----> VisualSource Free Site URL

Here basically i want to trap LDAP URL.

It seems i don't even need to use controller for this. And just capture the LDAP source URL in visualsource itself.

But so far i am not able achieve this in visualsource because it seems there is no onload event in <apex:actionSupport

Below find the code i am trying :

<apex:page setup="true" controller="MyController" showHeader="false">
<apex:form >
 <apex:outputpanel id="counter">
 <apex:outputText value="Click Here To Generate Session Id and Server URL" />
 <apex:actionSupport event="onload" action="{!doLogin}" rerender="refreshId" status="counterStatus">
 <apex:param name="serverHostURL" assignTo="{!apiHostURL}" value="{!$Site.OriginalUrl}" />
 </apex:actionSupport>
 </apex:outputpanel><br></br>
 <apex:outputPanel id="refreshId">
  <apex:outputText value="API1 Server Host: {!apiHostURL}"/><br></br>
 </apex:outputPanel>
</apex:form>
</apex:page>

Please let me know what i am doing wrong here.

Note : We want to use salesforce free site.

Any suggestions would be really help full.

Thanks Guys!
