Every time the system connects to the wifi AP, the BOSS(SpotPass) module itself will download the cleartext xml policylist: "https://nppl.c.app.nintendowifi.net/p01/policylist/3/<countrycode>". This policylist contains a list of SpotPass tasks for certain titles. This policylist can control whether the specified tasks are processed at all. The user-agent used for this policylist is: "PBOS-5.0/<printed hex u64 LocalFriendCodeSeed>-<unknown hex u64>/<text [[CVer|system]] [[NVer|version]]>/<unknown decimal value>/0".
In some cases the BOSS module will add the following URL parameter to HTTPS requests, when connected to a [[Nintendo Zone]] AP: "ap=<NZoneApNum>".

Every time the system connects to the wifi AP, the BOSS ("Background online storage service" = SpotPass) module itself will download the cleartext xml policylist: "https://nppl.c.app.nintendowifi.net/p01/policylist/3/<countrycode>". This policylist contains a list of SpotPass tasks for certain titles. This policylist can control whether the specified tasks are processed at all. The default user-agent used for SpotPass HTTPS requests(including this policylist) is: "PBOS-5.0/<printed hex u64 [[CfgS:GetLocalFriendCodeSeed|LocalFriendCodeSeed]]>-<hex u64 obtained via the friends service>/<text [[CVer|system]] [[NVer|version]]>/<unknown decimal value>/0". No user-agent is used for plaintext HTTP requests with SpotPass.
As of the policylist updated 2017-11-08, this stops the <tt>OlvNotf</tt> (Miiverse notification sync) task for <tt>000400300000bc00</tt>, <tt>000400300000bd00</tt>, <tt>000400300000be00</tt> for all regions and <tt>basho0</tt> for the [[Home Menu]]. Japan also has the <tt>9ER_NTD</tt> task blocked for いつの間にテレビ (<tt>0004000000034700</tt>).

SpotPass content can use this container to encrypt the payload and sign it, however SpotPass also supports downloading raw content without this container. The cleartext content is stored in [[extdata]]. The format of these headers is big-endian.

The hash at offset 0x12 hashes the 0x12-byte data at offset 0x0 followed by a zero u16. The RSA signature is signed by Nintendo. Following this header is the actual content payload, which is written to a cleartext file under the [[extdata]] /boss directory. The data following the payload header is written to extdata, but it's unknown what data is written to the extdata file before the content payload.
