Is it possible to render the same page differently depending on whether the entry was accessed directly or if it is a summary listing?

I have a weblog set up where the user enters the title, the body, and a summary.  I want to make it so that when the user goes to /myblog/ or /myblog/index, they receive a listing of the titles of the posts with the summary.  Clicking on the title will send them to /myblog/urltitle and will render the post appropriately.

The problem that I am having is that I would like some of the other content on the page to be different depending on whether it is a page for a single post the page for the listing of all posts.  What’s the easiest way to determine if the page is rendering a single entry or multiple entries?  I can’t simply use {if total_results == 1} because there could be only one item in the listing when i paginate the results.

I’m sure this is a common way of using templates and would appreciate it if someone could shed some light on the subject.

Thanks

Here’s the solution I came up with.  I’m using two separate {exp:weblog} listings.  The first checks to see if the url_title is the same as the appropriate url segment.  If it is, the single element will be rendered.  Otherwise, the entries will be listed in a summary format.

Pretty cool you posted your own solution (and only 1 hour later )
