Hi Rob,

Thank you for your quick response, but I see that the aliasing doesn't
work fine as I thought it was all along.. Here is why I think so..

For your understanding, I put up a sample comparison page that
contains embedded gadgets from both the original url and the new one.
Here is the sample page :
http://www.freewebs.com/udaysasi/comparison.html

The URL A in the page was used when Google Pages was on. When the
Google Pages service was shut down, I moved my gadget to the Google
Code (URL B) and filed an aliasing request for A to B. By then, my
gadget was embedded on a lot of sites, (I see about 3 million page
views every month on Google Analytics).. Most of them have the old URL
A.

Not until recently did I notice that those webpages are serving very
old version of the gadget, and hence changes I made over the past year
or so never reached those users.

So, My question is - Is this expected behavior? In other words,
Whenever I make changes to the gadget, should I re-file the aliasing
request?

Thanks in advance for your help.

-Uday
