Get the URL of the page on which the post is located

[rygel]

Is it possible to add a function which returns the URL of the page on which the post is located?

For example there are 15 posts, 5 posts per page, and the post "blah" is on page 3.
I want to display on the post "blah" a link back to the page where it is located (page 3). This needs to be dynamically adjusted by Poet, because if new posts are added the post "blah" will move to page 4, etc.

Thanks!

Maybe you can have something like this:

then you can use the pageURL() helper function to get the page url
