How to deactivate pdf function in Joomla

Joomla has bundled Its pack with the ability to convert document into pdf file by clicking on the pdf icon  when we view the document or by typing the web address with ending “.pdf’

For example, If you have a document located at :

http://www.yourdomainname.com/file.html

You can generated pdf in joomla by typing the address like this :

http://www.yourdomainname.com/file.pdf

Sometimes, this pdf function is frequently utilized by pdf search engines like below :

• http://www.pdf-search-engine.com
• http://www.pdfdatabase.com
• http://pdfstack.com
• http://ebook-search-queen.com
• http://www.pdfqueen.com
• http://www.docjax.com

If someone, named John, is looking for a pdf document on pdf search engine, and John found it and it links to your web and John clicked it to access the document, usually the pdf search engine call that pdf document from your web and show it to John.

If you see on the cpanel log of your hosting, it was accessed by the pdf search engine and it was not accessed by John. The IP address is belong to the pdf search engine.
