Refer

The link below uses the refer script, which is used to stop other web sites from linking to your important files. Clicking this link will download "refer_sample .zip" (a compressed file containing a sample image). However, the link will not work from another site. Instead, the user will see a message telling them to visit your site to download the file.

For more information about the refer script, as well as samples and guides for other free web tools and scripts, please see the Refer Guide.
