- Add `Proxy.certificate_check` setting (defaults to true for secure production) - Add `compute_host_header()` to properly format Host header with non-standard ports - Extend `ensure_origin_backend()` with certificate_check parameter - Include cert setting in backend name to avoid reusing backends with different settings - Add comprehensive tests for port preservation in proxy signing and HTML rewriting - Update all call sites to pass certificate_check=true (secure default) This fixes an issue where backends behind reverse proxies would generate URLs without the port when the Host header didn't include it.
- Add `IntegrationHeadInjector` trait allowing integrations to inject HTML into <head> - Add `with_head_injector()` builder method to IntegrationRegistrationBuilder - Add `head_inserts()` method to IntegrationRegistry to collect all injector snippets - Update html_processor to inject integration head inserts after TSJS bundle This enables integrations like GAM to inject configuration scripts into the document head without modifying the main TSJS bundle.
- Add `GamIntegrationConfig` with enabled, bidders, and force_render options - Implement `IntegrationHeadInjector` to inject GAM config script into <head> - Register GAM integration in the integration builder system - Add unit tests for config script generation Configuration example: ```toml [integrations.gam] enabled = true bidders = ["mocktioneer"] # Only intercept these bidders, empty = all force_render = false # Force render even if GAM has a line item ``` The injected script sets `window.tsGamConfig` which is picked up by the client-side GAM interceptor on initialization.
