I've a site (Apache) that is called every 2 minutes to check it is up
(and if not, email is sent and pagers are alerted). It does this by
asking for the "webping" URL.

There is no such page, so an error message goes back (enough to show
the server is running), and an entry is added to the error log.

Is there a way to stop this particular page being added to the error
log, as the genuine error messages are going unnoticed. I could create
a "webping" page, but then it's going into access.log and counting as
a hit, which is also undesirable.

Any ideas?

That's an interesting thing...
Where do I have to make changes if I want to prevent entries in the
access.log? (I don't want to have loggeg accesses to *.gif and *.jpg
files)

Thanks
Michael

You can change the code to say that, but don't expect it to compile
since that isn't valid LISP.  Well, it isn't valid C either.

The easiest solution would be to used a piped error log (see the
ErrorLog docs for how to set it up using |program) and have your
program filter whateve rit wants.

Use a piped log.  See the TransferLog docs for details.

Then you can have your program arbitrarily filter anything you want,
rot13 all your logfiles, change the datestamp to look like
it is from 1923, etc.

I was editing SAS and Perl scripts before and there it is 'eq' what is
'==' in C. This will compile (of course after deleting the lines
between /* and */).

Good try, but it still won't quote work.

Hint: strcmp.

You are far better off just logging to a pipe and letting it filter.

Now we got it. Seems to be a very inefficient way to come to a
solution. Thank you, Marc.
if(strcmpi(r->filename,"g:/apache/www/q.html")==0)  (thanks Darren)
Of course you are right, filtering with a pipe is much more better
because its flexibility. But it takes more resources.
