As an alternative to the
X
Offline XAMPP BSB
you can use the nearly same BSB protocol
with an
online web server —
— but you should
protect it through
authentication technology, such as
a login protocol that creates an
IP-bound authentication cookie.
The BSB.php should check this cookie
(or performs some other suitable tests)
and
exit without doing anything
if the authentication fails.
For
details, study web server programming
and internet security protocols technology,
for instance via textbooks on these subjects.
