How to use tags to adjust Pepper’s intonation

Pepper Voice

This table represents the values  to set in the tag of the table it’s used to set Pepper’s voice:

HEXA: Programmable, Highly Maneuverable Robot

Robots are the next big platform. We’ve all dreamed of a world where robots interact with and help humans in their daily lives. But the reality is, robots have a long way to go. Limited access, due to robots being either too expensive and complex or too simplistic, has kept innovators, explorers and the masses at bay.

Caching requests by HTTP status code

Sometimes you may want to cache request based on the status code with a different TTL.

Adding the following in the vcl_backend_response will help you in achieving the result:


if (beresp.status == 403 || beresp.status == 404 || beresp.status >= 500)
{
   set beresp.ttl = 60s;
}
