Returning A Custom Block Page

It is possible to return a customized block page instead of PX default one.
The block page returned by Fastly Enforcer is defined in the subroutine px_custom_create_block_page in px_custom.vcl file.
To set your own block page, set the req.http.X-PX-block-page header to a string containing the html of the desired block page.
For example:

1sub px_custom_create_block_page {
2  set req.http.X-PX-block-page = {“<!DOCTYPE html> <html> <body> block page </body> </html>”};
