Question

I found in iOS simulator, there is a file named Cache.db in Library caches path.

There are some tables in the db:

sqlite3 Cache.db 
SQLite version 3.7.5
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .table
cfurl_cache_blob_data       cfurl_cache_response      
cfurl_cache_receiver_data   cfurl_cache_schema_version

I want to know what does it do? And how can we make use of this db?

Answer 1

That is used by NSURLCache. It is automatically used when you create a NSURLRequest unless you specify that you do not want to use cache.
