Update 11/17/2009: Code released.

Description

The lccOffsitePortalAuthentication (ASP Code) performs a type of proxy service. It allows you to do a background connection to an offsite portal (that utilizes IP authentication), retrieves the cookie, then redirects the user to the portal, allowing them to utilize an outside portal with the proper cookie, but, from an IP outside the authorized range.

This type of process only works with sites that allow access beyond IP authentication, with a provided access code (i.e. id/password, etc..).

There are two sets of the code below. One is the code to 'fill-in', the other is an example of how it would look when filled in.

Requirements

fill-in siteLicenseId
fill-in siteLicensePassword
fill-in siteLicensedURL
fill-in siteLicensedURLPath

ASP Codet

Template Code

<%@language=VBScript%>
<%Response.Buffer = True%>
<%
Response.CacheControl = "Private"
DIM retrieveCookieURL, postCookieURL, siteLicenseId, siteLicensePassword, siteLicensedURL, siteLicensedURLPath
Const WinHttpRequestOption_EnableRedirects = 6
siteLicenseId = "[fill me in]"
siteLicensePassword = "[fill me in]"
siteLicensedURL = "[fill me in]"
siteLicensedURLPath = "[fill me in]"
retrieveCookieURL = siteLicensedURL & siteLicensedURLPath & "?USERID=" & siteLicenseId & "&PASSWORD=" & siteLicensePassword
set xmlHttp = Server.CreateObject("WinHTTP.WinHttpRequest.5.1")
xmlHttp.Option(WinHttpRequestOption_EnableRedirects) = FALSE
xmlHttp.open "GET", retrieveCookieURL, false
xmlHttp.send
postCookieURL = siteLicensedURL
Response.Redirect postCookieURL
Response.Flush
%>

Fictitious Example Code

<%@language=VBScript%>
<%Response.Buffer = True%>
<%
Response.CacheControl = "Private"
DIM retrieveCookieURL, postCookieURL, siteLicenseId, siteLicensePassword, siteLicensedURL, siteLicensedURLPath
Const WinHttpRequestOption_EnableRedirects = 6
siteLicenseId = "someSiteId"
siteLicensePassword = "somePassword"
siteLicensedURL = "http://somesite.somewhere.com"
siteLicensedURLPath = "/index.php"
retrieveCookieURL = siteLicensedURL & siteLicensedURLPath & "?USERID=" & siteLicenseId & "&PASSWORD=" & siteLicensePassword
set xmlHttp = Server.CreateObject("WinHTTP.WinHttpRequest.5.1")
xmlHttp.Option(WinHttpRequestOption_EnableRedirects) = FALSE
xmlHttp.open "GET", retrieveCookieURL, false
xmlHttp.send
postCookieURL = siteLicensedURL
Response.Redirect postCookieURL
Response.Flush
%>
