While it was running, 4D was running at about 90%+ of memory, until kaboom.

Steve,
No judgement here - but this "resolution" was really just a patch you put in

Totally appropriate, IMHO. The problem is the test. When the problem is the
problem, look at that. I’m guessing for 98% of websites powered by 4D, a DDOS
is highly unlikely.

Hi Steve,
Isn't that just patching for the test instead of the problem the test is
trying to identify? Or am I missing something - which is entirely possible?

Neil,
I can probably operate on the basis that my customer will want to test this
without a firewall...
I just need to be prepared for everything.

> Anybody know a security scanning service that doesn't break the bank?
Nessus used to have a community edition that was able to get gotten and used
for free in non-commercial environments... it looks like they renamed this
option to "Nessus Home"
So... back to my original question:
Anybody know a security scanning service that doesn't break the bank?
Or a tried and true simulator that I can use to test.
I've been using "LOIC" (Low Orbit Ion Cannon)
However, my app seems to handle this no problem.
Been running from 2 different systems
Hi Randy,
One of the things that the "security scan" is probably finding is that HTTP
TRACE is enabled.
Starting with v16 this has been disabled by default and there is now an option
to enable it.
http://livedoc.4d.com/4Dv16/help/Title/en/page8822.html#3101893
I suggest testing with v16
Hi Tim,
RE: Didn’t v15R5 also cure the crashing during those scans?"
Thanks for chiming in.
I'm not finding any reference to crashing during scans in the v15R5 release
notes/bug fixes.
Did I miss something?

I thought most firewall routers will stop a DDos attack before it hits your 4D
server. Was this not the case for you or are you testing without a firewall?

Randy,
We have several customers who were using commercial scanning software to test
web servers and one test was basically of DOS. When this test was run, 4D
Server (V13) would crash...not good.
To get around this, we did a rather simple "trick"
