Hi,

I am facing the following problem. Please help me to resolve it.

I have a demo website consist of 3 pages.

  1. Home_mc
  2. Safety_mc
  3. Portfolio_mc

The second page Safety_mc has some external links to .pdf & .jpg files. When I am on Safety_mc page and click a link it opens a pdf file in same window it is fine. But when I click on back button on web browser, it takes me to Home_mc instead of Safety_mc. How to resolve this problem?

Please help me.

Thanks in advance.
