Is nginx sub_filter rewriting?

I am trying to rewrite the body links of a proxy page using something like this:

    sub_filter http://proxied.page.come http://local.page.com;
    sub_filter_once off;

Is this even the way to go? What is the difference between sub_filter module and substitutions_filter

Can a variable in delcaration sub_filter also be used?

Ideally, you should ask the backend to write the correct links. Although you can fix some simple cases with a subfilter, this is not something at all possible (for example, if the returned data is not text, but, for example, a flash code).
