SureRoute and test objects
When enabled, SureRoute evaluates alternate Internet routes to use the fastest way to deliver your non-cachable content from your origin server. When disabled, your traffic may travel along a different, less efficient route.
SureRoute improves performance by routing requests from your users along the fastest network paths. Simply place a valid test object, such as the Akamai SureRoute Test Object (SRTO), on your origin server. This allows SureRoute to detect the best path for your traffic when traveling between the Akamai servers and your origin server.
A test object is a static text file that acts as a stand-in for the data that you’re sending on the network. Akamai frequently requests the test object via a number of available routes. The fastest route tested carries all your traffic until the next test is run.
A valid test object must:
- Give an HTTP 200 response and does not require authentication
- Be a static text file of content-type text/HTML
- Be approximately the size of an average page, but no less than 8 KB
- Not contact a database or do other back-end processing
SureRoute option: Always request test object with HTTPS
If your site only serves secure traffic via HTTPS and doesn’t respond to HTTP, you’ll want to enable this SureRoute option. Enable this setting to ensure SureRoute race requests to your origin use HTTPS only.
