Closing connection on certain hits

Is there a module to do this?

My weblog is constantly under a stream of spam attacks. Fortunately the attacks rarely hit a working script, because over the years I've renamed scripts and put commented-out forms on my pages which throw their spamming scripts off. However a number of spammers keep hitting these absentee scripts no matter whether they get a 404, 403 or other response.

So rather than bother with serving them a response, I'd like to close the connection without sending any headers or data in order to minimise the server impact and possibly give their scripts a more direct hint. Due to the nature of the hits, I can only detect them by the URL they hit.

Are there any Apache modules which could do this? I'm using Apache 1.3.37.

I'm not sure about this as I've never tried it, but maybe a "Connection: close" header would do the trick.

Thanks zomega. I ended up with a Perl script which did this:
print "Status: \nConnection: Close\n\n";

That closes the connection with a null status (I tried without the null status and Apache filled in a 200 status for me).

It's not a perfect solution since Apache has to process the perl script, but hopefully it'll give the spammers the mesage.
