[cellml-discussion] Disabling the PDF action on the CellML website for anonymous visitors

[Gareth de Walters]

Hello Everyone,

This email is to notify you that the PDF action on the CellML site has  
been disabled for all anonymous users. It was necessary to turn off  
this feature to prevent search engines repeatedly calling the PDF  
action each time the robots indexed the site. Our observations  
indicate that during these episodes the volume of calls to the PDF  
conversion action becomes so great that all sites on bioeng2 are  
rendered unresponsive.

The PDF link in the 'View Math' view of the CellML Model Repository is  
not affected by this change, and remains visible to anonymous users.  
The PDF link on each page of the CellML site is visible after members  
login.

regards, Gareth
