We'd like to enable caching for the subset of #RESTBase's endpoints pertaining to the #Mobile-Content-Service on the text Varnishes. Specifically, the following URIs should be cached:
- `https://{domain}/api/rest_v1/page/mobile-html/{title}`
- `https://{domain}/api/rest_v1/page/mobile-sections/{title}`
- `https://{domain}/api/rest_v1/page/mobile-sections-lead/{title}`
- `https://{domain}/api/rest_v1/page/mobile-sections-remaining/{title}`
- `https://{domain}/api/rest_v1/page/mobile-text/{title}`
[PR 317](https://github.com/wikimedia/restbase/pull/317) introduces the HTCP purging logic into #RESTBase, where all of #Mobile-Content-Service's endpoints are purged from the cache as soon as an update job for a specific title is received from the job runners.
Note: the purging logic has been tested in the #Beta-Cluster (cf {T113235}) and verified it works.
