/*
EverestTechTrack.js.
This file makes a request for a 1x1px tracking image on either the email capture page or the order results page.

The query string variable ev_transid takes this format:

020080818092416948429952_264805997
^\---------------/\----/ \-------/
|        ^           ^       ^
|        |           |       |
|        |           |       - customer UID taken from Fool cookie (will be blank if cookies are disabled)
|        |           |
|        |           - random number between one and one million
|        |
|        - Current time (year, month , date, hours, minutes, seconds, 1/1000th of a second)
|
- Use 0 for email capture page, 1 for order page

Can't include the Ecap function on WWW\Usmf\Shop\Newsletters\Landing\Template\EcapTemplate.xslt
as our XSLT processor chokes on "&", even within the CDATA section.

The second query string variable takes this format:
ev_ecap_<product number>=1
