Robots.txt Disallow

If I add line in my robots.txt

Disallow: /site/contact

is this the same as I put nofollow on every /site/contact link?

The topic is not Yii related, I moved it to Miscellaneous.

Yes. If crawlers really respect that is another issue, though.

Not really the same… with "disallow" the crawler should not "crawl" the site/contact page at all… by having only nofollow on links the page at site/contact would be "crawled" and possibly returned as a search result.
