clear html webpage?

i am currently developing a crawler that crawls all links on the web and displays them in the web browser (and saving it of course).

but after some hours there will be a huge list displayed on the web browser and i want to only display lets say 1000 links at the same time. then i clear the html and display another 1000 links. this is also good for the RAM or it will eat up all memory.

how do i clear the web browser screen?

EDIT: i have seen some scripts using some flush buffer functions. has this anything to do with my case?

You can use document.write('') to completely delete the contents of the web page without reloading it.

Pagination: What is it and how to do it? Sounds like you're describing a perfect opportunity to paginate your results.

If you want to clear the screen in a way that saves memory on the client's side, you'll have no choice but to do redirect to a different page, e.g. using JavaScript: location.href="...". That will trigger the loading of a completely new page though, so you would have to save your crawler's state and continue from the saved point.
