Hokku about HTTP responses

I found here on the Internet haiku for 404 errors:
The site you are looking for is
impossible to find, but you
can’t count others ...

and decided to come up with more ...
401
Enter here
Only the initiate can.
Is that you?

403
The owner didn’t tell
Speak with a stranger to
His site ...

500
I didn’t fulfill the request
That site, but
I tried ...

410
The site you were looking for
Has sunk into oblivion - Don't look for it more ...

400
To understand the speech of a stranger
It's hard for a simple site - Try differently ...

Maybe I and not original in this, but I really wanted to show off.
