I don't really know how to solve following problem: When I access
.../users/1 I get the website and the user is shown properly, all good.
I have some link_to_remote actions on my website and when they call the
/users/1 action I - of course - get the whole page rendered despite I
just wanted to update a div with only name being displayed. My question
now is how it's possible to determine within the action if it's an HTTP
or AJAX request and render accordingly (full layout for HTTP and only
one DIV box for the AJAX request).

I'm sure you know this but AJAX requests are of course http
requests :-).
There's the xml_http_request? method (also available as xhr? ) and of
course respond_to is designed for this sort of stuff.

How would you solve that kind of problem?
I may be misunderstanding your question but I think you just need to
wrap the rendering, and potentially some of the actual logic, in a
respond_to block.
respond_to do |format| {
format.html { ... }
format.js { ...}
end
respond_to selects what's to be rendered not on whether it's an ajax
request or not, but by the acceptable mime types in the request. An
ajax request might be requesting html.
request.xhr? is the proper way to detect an ajax request.
