Hi

An easy one for someone who understands .htaccess syntax.

To stop external links going to a page deep within my site and instead to
take them to the home page, I want to redirect all page requests that have
either blank or referrer information other than from within the site
itself. I don't want to use Javascript and think that this can be done in
.htaccess  using something along the lines of:

	RewriteEngine on
	RewriteCond %{HTTP_REFERER} ^http://www\.somewhere\.com [NC]
	RewriteRule \.png http://www.somewhere.com/somepage.htm [R]

but with the RewriteCond negated so that any referrer (including none) gets
redirected to the http://www.somewhere.com/somepage.htm URL.

How do I negate the RewriteCond statement and make in include no referrer
(or is this one and the same)?

TIA

So
	RewriteEngine on
	RewriteCond %{HTTP_REFERER} !^http://www\.somewhere\.com [NC]
	RewriteRule \.png http://www.somewhere.com/somepage.htm [R]

is this the correct syntax, the Apache documents assume more than a very
basic knowledge of C type condition tests.

Thanks

The problem is that the site is live and gets a lot of visitors, so I can't
afford for it to be down while testing the syntax online.

If you don't have another hosting account you could use to test it 
(ideally on the same server) then it might be worth installing Apache on 
your PC - easily done with XAMPP

http://www.apachefriends.org/en/xampp.html

to test it locally before deploying it.

Thanks. 

I've installed xampp on a virtual Ubuntu box and I'm currently trying to
configure it (Unix is not my strong point!).

Testing is very easy: Create a folder

   http://www.example.com/myhiddenfolder/

which only *you* know, and make your tests in "myhiddenfolder".

BTW:
Use  http://www.example.com/
     http://www.example.net/
     http://www.example.org/
when you need dummy addresses.

This is fine for testing new pages and javascript tweaks, but I need to
test a revised .htaccess.

I do have a 'spare' sub-domain name that currently just points to top level
site, so if I pointed this so that http://www.spare-example.con pointed to
http://www.example.com/myhiddenfolder and I put the test .htaccess in
http://www.example.com/myhiddenfolder, would this work or would Apache only
use the .htaccess in http://www.example.com/ ?

Thanks

That won't have passed him by.  Unless you have a very odd
configuration, .htaccess affects the folder it is put it (and, where
it makes sense, those below).

Yes, but it would also work without re-pointing the spare domain.
Accesses to http://www.example.com/xyz would be unaffected and
accesses to http://www.example.com/myhiddenfolder/pqr would be based
on the referer.

 http://www.example.com/.htaccess
applies to  www.example.com  as a whole,
which includes  www.example.com/myhiddenfolder/ .

 http://www.example.com/myhiddenfolder/.htaccess
applies to  www.example.com/myhiddenfolder/  only -
but it overrides any settings in  www.example.com/.htaccess .

Andreas & Ben

Thanks. I've changed the forwarding of my 'spare' domain to point to a test
area (with a modified style sheet so I can check the forwarding is set
correctly) then I can have a hack at the .htaccess.

Thanks to you both and to Dominic for your help.
