Please ask the question in the message body, as clearly as possible. No not
refer to the Subject line or imply its content in the body. ObHTML: The same
applies in HTML authoring: <title> is necessary, <h1> is almost always
essential, but neither of them should be referred to or implied in the rest
of the content.
So you apparently want to "Redirect to link nr 2 if link nr 1 is not
working". This is not possible using <meta> tags, or any HTML tags.
The conclusion is that you should probably put two (or even more) alternate
links on your page, if you expect that the first one might fail often. This
is quite simple - and sites that offer software for download often use such
a tactics, perhaps offering the user a fairly large list of links that all
do the same thing (when they work). But two, or maybe three, should normally
be enough.
Server-side, you could implement auto-redirect in a sense. Your <a
href="..."> would then use a URL that invokes a server-side script, which
accesses a URL where the content resides, and sends it to the client; but if
the operation fails, it could access an alternative URL, etc. However,
there's not much point in this, as a rule. It fails when the system where
the script resides is not available. And if you trust that system so much
that this does not matter, why don't you put the content proper on that
system and use simple URLs to it?
