I recently purchased something from a website and during the checkout proces
s my credit card number was automatically filled into the credit card number
 field.  The numbers were also completely visible instead of hidden by dots,
 astericks, etc.  I know fr
om experience on other eCommerce websites that this is not best practice.  A
fter sending an email to the webmaster, I was informed it was a browser issu
e instead of an issue with the way the developers had programmed the page.  
I believe this to be incorr
ect, but need someone with more knowledge than me to help out.  Here are my 
questions.

1)  Where can I find information on how to appropriately code a checkout pag
e so the autocomplete feature is not enabled for the credit card number and 
expiration date ONLY?

2)  Where can I find information on how to code a page so the numbers entere
d into a field are not shown, but instead are replaced with astericks, dots,
 or whatever?

3)  How can I clear my credit card number from the autocomplete cache so it 
cannot be read by anyone else trying to gain access to my computer?

I really appreciate all of your help!
