Compression & Optimization Deep Dive

Overview

Compression (gzip, brotli) reduces bandwidth.

Core Concepts

• Accept-Encoding request header
• Content-Encoding response header
• OkHttp handles automatically
• Saves ~60-80% bandwidth

Code Examples

// Already transparent in OkHttp
val httpClient = OkHttpClient.Builder()
    .addNetworkInterceptor { chain ->
        val response = chain.proceed(chain.request())
        // OkHttp automatically decompresses
        response
    }
    .build()

Senior-Level Insights

• Compression trade-off: CPU vs bandwidth
• For images: compress beforehand (WebP, HEIC)
• Disable for pre-compressed (videos)
