Apache(mod rewrite) or Acrobat or hosting problem

[hagai]

Hi, I got a weird problem that doesn’t make sense to me.

I have concluded that it must be a problem with one of the following;
Apache's mod rewrite (doubtful)
Adobe Acrobat reader (maybe)
Bell web hosting (probably)

My .htaccess file look like this;

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^

http://w*\.mypage.com.*$

RewriteRule ^.*

http://w*\.mypage.com

[R]

Simply put, if you try to access a file outside of my page you will be redirected.

Now the problem occurs when I try to view a pdf file in this directory. The error I get from acrobat is "File does not begin with '%PDF-'". However it in fact does start with '%PDF-' and when I remove the .htaccess file I am able to view the pdf file. Text files are not affected by the .htaccess file.

I have a bad feeling that this is a hosting problem.

Does anyone know if this is an Acrobat issue or a web hosting issue?
Any way to get around it without removing the .htaccess file, that’s a security measure I can’t live without?

PS. It has been my experience that Bell Web Hosting is bad. I would not recommend anyone using it.

Thanks for your help
