I recently re-designed a web page. As part of the re-design, I used eight named anchors to allow people to quickly jump to specific categories on the page.
The problem is that when someone clicks on a category link, in the URL bar the link changes from www.mysite.com/mypage.htm to www.mysite.com/mypage.htm#category1
Normally, this isn't a huge deal. However, on one particular long-established page this is causing a few issues since people click a category, scroll around and then click a link on my page that leads off-site, then hit their browsers back button to return to my page. The problem is that when people come back to my page, they often aren't going back to precisely where they were due to the named anchor in the url.
That is standard browser behavior. Every site out there that uses named links will behave that way, so trying to customize your own site to behave differently is not a good idea. Also, what you're asking is not really possible.
