getURL and cookies

For some time, my PB10 app has happily been using a getURL call to retrieve HTML from a site.  Recently, a cookie is now required to access the same URL.  After permitting the cookie to be set, I can access the page in a browser, but how to provide the cookie info when accessing from PB?

Here is an example:

ls_URL = "http://www.tsnhorse.com/cgi-bin/instant.cgi?type=inc&country=USA&track=SA&date=2006-03-26"
getURL (ls_URL, this)

This used to work fine and return valid HTML to the data blob (i.e. as viewed in a browser), but now rather returns a page informing the necessity of registration, which simply places a cookie on the user computer.  After the cookie is placed, browsers work fine, but not the PB  app because, I presume, the cookie info needs to be passed.  How do I append the Cookie header item to the ls_URL value, so that it is treated during the HTTP GET as a separate Request Header item, and not part of the  main Request-line?

Example cookie info is: Cookie: EMREG=myname@mydomain.com; REGISTERED=TSN_INSTANT_CHARTS

Or, is there an alternate to PB 'getURL' for such detailed processing,  perhaps by a PBNI, or external ActiveX?

Thanks,

Ted
