Feature Flags Behind a Proxy: HTTP Proxy vs ConfigCat Proxy
· 12 min read
Feature flags need a way to receive configuration updates. In many setups, that means an outbound connection, but restricted networks can make that impossible.
If your backend sits behind a corporate proxy, outbound requests may need to pass through an authenticated gateway. In a locked-down VPC or air-gapped environment, direct internet access may be restricted or unavailable entirely. When the SDK cannot retrieve a usable configuration, it may continue using the last cached version or fall back to configured default values. Either way, the "flip a switch" experience starts looking a lot less dynamic.
