Okhttp: Wiki page all about caching

[swankjesse]

Stuff like:

• HTTP caching heuristics source?
• what it means if cacheResponse() and networkResponse() are both non-null (issue #4539)
• why you need to read the entire response before an entry is stored
• the cache must not compete with other processes for the same directory
• pruning the cache manually

Also how to avoid network when there is a viable cache entry.

        // Use the cache without hitting the network first
        // 504 code indicates that the Cache is stale
        val preferCache = CacheControl.Builder()
            .onlyIfCached()
            .build()
