Hi Friends,
My question is that on the web page if somebody is not able to access a web page then I would like to display a Hyperlink on the page so that a user can select that hyperlink and then download software which is necessary Which will make that page visible to the user.

Here is the whole thing,When user visits web page and if he doesn;t see web page then a Hyperlink should become visible and this hyperlink should become only visible if the user cannot see webpage,those users who can see web page should not see it.

Can somebody help?
