Advanced Zone Settings

All about The “Advanced Settings” tab in the NetDNA™/MaxCDN™ Control Panel

When you login to your NetDNA™/MaxCDN™ control panel, and click on “Manage” next to your Pull/Push Zone, the 4th tab in the navigation is called “Advanced Settings”. The “Advanced Settings” tab contains a number of options that are used for advanced zone configuration and extra functionality.
Advanced Settings for Pull Zone:
HTTP Referrer Protection: This feature works exactly like HOTLINK Protection, basically it limits access to your assets to certain domain(s) and blocks direct access or access from any unauthorized domain; which prevents leeching and saves bandwidth.

Query String:
The Query String option allows you to cache multiple version of the same file. For files with multiple versions (i.e: myscript.js?v=1.2.3 and myscript.js?v=1.2.4) you need to enable Query String in order to cache all versions. Otherwise the file won’t be cached correctly Content Disposition:
Content Disposition will set the Content-Disposition header for every file in this zone. This will force all files to behave as if the end-user chose the “Save As” dialog; just like “Right Click -> Save target As” in your browser.

Custom Robots.txt:
This feature will add a robots.txt to the root directory to disallow page crawl by search engine like Google , this will prevent content duplication on Search Results. Override Cache-Control Header: This feature ignores the origin Cache-Control Header and sets every request to have a Max-Age of: No Override, 1 day, 7 days, 1 Month and 12 Months (default – no override). This option set a Cache Override on OUR Servers, means it will ignore the expiry header on the origin server and use a custom header which is defined by what you select from the drop-down menu

Set Default Cache Time:
This feature sets any request with a no “Cache-Control header” from the origin to stay on the server: 1 day, 7 days, 1 Month and 12 Months (default 1 day).

Advanced Settings for Push Zone:
HTTP Referrer Protection: This feature works exactly like HOTLINK Protection, basically it limits access to your assets to certain domain(s) and blocks direct access or access from any unauthorized domain; which prevents leeching and saves bandwidth.

Expires Header:
This feature allows you to set an expiry header for your Push Zone contents like you do with Pull Zones, you can manually set the expiry header to your preferred amount of hours or days.

Content Disposition:
Content Disposition will set the Content-Disposition header for every file in this zone. This will force all files to behave as if the end-user chose the “Save As” dialog; just like “Right Click -> Save target As” in your browser.
