hello there...
i have a system which uses frameset to view another html page, lets say a.html ..
this a.html is actually an excel file which has been saved as html..in this file, I have made a list of movie title. once a user click on the title, it will open the movie's poster in a pdf file format.
my problem is that, once the user click on the movie title (in a.html), it will open the pdf file in the same page as the a.html is..i want it to open in a different tab ; 1 tab is used to view the movie title, and another tab is to view the poster in pdf file.
is there any ways to do this?

The Home.aspx.cs code should verify for the logged user and if it is not identified it should redirect to Login.aspx. There will never be a render of the frameset on Home.aspx since the redirect will take place so the other pages will not get called. Maybe you have a static Home.aspx page where the frameset is always displayed and you have something like content.aspx on the center content area? You need to verify for logged user on your home.aspx, not on your main content aspx page.

Using the target attribute will do this, so the anchor tags for the movie titles would be <a target="_blank" href="pathtofile">
Note: The target attribute is deprecated by w3c; it is invalid code in strict DTDs, but since you're obviously using a DTD which allows framesets that shouldn't be a problem.
