[Hari]

Hi

while running test cases on internet explorer we are using *iexplore and some times *iehta.

what are the difference between *iexplore & *iehta?

could you explian the differences with examples.

iehta is a mode of execution of IE having higher security privileges.
Since Selenium RC uses java script heavily, it suffered from a security restriction called same origin policy because of which you may find troubles with -

1. Having to change domain from http to https.
2. File upload

etc

iehta mode is supposed to overcome these js related restrictions.
