Right, so it will be an arbitrary comparatively small allowance I will
make, and then politely refuse to handle anything larger.

Thank you all for your assistance.

I don't believe we limit URL length per-se, though they get interned and as
such four gigabytes per URL is probably the absolute limit.  In addition, POST
data is nominally unlimited though I believe we have a similar four gigabyte
limit.


So if you want to store any possible URL plus POST data you'd need eight
gigabytes per allocation.

statically-sized buffers for the worst common case, especially in a
piece of software that might be storing information on tens of thousands
of URLs (Everything in your history, the links to all the resources on
every page you have open, etc).

My advice is firstly to either measure and then allocate, or read in the
data and reallocate as needed dynamically.  Secondly, use a different
language; BBC Basic really isn't good for this sort of thing :)  (If
using a modern interpreted language like Lua, Python, or even Perl,
asking this question would never have occurred to you.)
