Not quite sure if this is what you want... I have several surveys that have what I term as "short URL's" using the following in the Apache httpd.conf (at the very end or in the vhosts.conf if you have that enabled):
Redirect /YOURXXX /index.php/survey/index/sid/YOUR SURVEY NUMBER/newtest/Y
You will have to restart your Apache. What this does is accepts any URL with /YOURXXX at the tail and redirects to a specific survey.
For example, I have a depression screen survey at http://myhost/phq and I use the following in my httpd.conf:
Redirect /phq /index.php/survey/index/sid/518477/newtest/Y/lang/en
