Closes #15710.

Add the typed mediaTypes.video.cache option. Setting it to false skips remote and local caching performed by Prebid.js for that ad unit's video bids. Omission and true preserve existing rules. Cached and opted-out units can share an auction without changing global configuration, including when auctions overlap. Audio caching on mixed audio/video units is unchanged.

This option does not disable caching by Prebid Server or bidders. Supplied VAST URLs and cache keys are preserved, even when cache.ignoreBidderCacheKey is enabled. For outstream video, cache: false takes precedence over renderer-driven caching: an XML-only bid is rejected if its active renderer requires a VAST URL. A supplied VAST URL remains usable.

Documentation: prebid/prebid.github.io#6784.

Validation:

• Full npx gulp test-only --browsers ChromeHeadless: 26,126 passed, 7 skipped, zero failures.
• Actual auction cases cover mixed audio/video units, remote/local caching, and supplied cache keys under opt-out. The audio regressions fail before their correction.
• All four changed executable lines are covered by the affected browser specs. Scoped gulp lint --nolintfix, TypeScript checks and git diff --check pass.
• Six Fluid Player 3.60.0 playbacks completed on executable head d12d5e8f5 in Chrome 155. Both cached and directly consumed VAST played, tracked completion and resumed content. Mixed auctions made one cache POST; the default control made two. Later edits only clarify JSDoc and add a contract regression. This used controlled bids and a local cache endpoint; production publisher deployment remains untested.
• A request-converter probe confirms the option leaves the separate Prebid Server cache policy intact.

Maintainer label request: feature, minor, core. My fork account cannot apply these labels.

looks like some conflicts. and you might have to alter the logic a bit because requiresVastUrl in master branch will still trigger cache. so just need to have it check your cache: false logic also.

Merged current master and applied cache: false to the requiresVastUrl path too. The regression cases cover both renderer fields and local rendering, plus bids that already have a VAST URL.

This PR introduces changes that may not work on all browsers. According to Babel, the following polyfills may be needed, and they are not automatically included:

• Changes to test/spec/auctionmanager_spec.js may need:
  • es.json.stringify
  • web.url-search-params.delete
  • web.url-search-params.has
  • web.url-search-params.size

The best way to address this is to provide good test coverage, as normal PR checks run unit tests on older browsers.
