In RISC OS terms, it's another way of saying "limited by available
memory"...

Due to the problems that the Wimp has changing the allocation of writable
icon buffers, there's an arbitrary limit (255 characters, perhaps?) in the
RISC OS front-end's URL bar. If the core tries to display a longer URL, the
bar is just cleared and you get a warning -- but it doesn't otherwise affect
the browser's operation.

This obviously means that there's a limit to the size of URL that you can
type in, too. But that's it. You can follow any length of link in NetSurf,
and launch any length of URL via the launch protocols.

All subject to that 4GB limit, of course.

At which point the Web server (lighttpd) logs it as an error.

It's probably much greater than that on modern systems, too!

I just can't believe that a URL can contain 33% more letters than the
King James Bible's 3,116,480.

"four gigabytes per URL"

LOL
