iPhone cache limits

Mobile Portal

Provide a simple portal for access from devices with low bandwidth/screen sizes/ CPU.

This acts like the '/m' version of popular websites.

This should be light on AJAX (if present at all).

This can use the existing RESTlike CRUD controller's ?format=plain to generate lightweight forms.

JavaScript caching:

Safari for iPhone will only cache files 25 KB or smaller served using the Expires explicit expiration time or Cache-Control max-age directive HTTP headers. Safari decodes the file before saving it cache, meaning your total unzipped file size must squeeze under the 25 KB ceiling to hit the cache. Components already in cache are only replaced by new cacheable components using the least recently used algorithm. Safari for iPhone is able to cache a maximum of 19 external components, placing a maximum cache limit at around 475 KB.

Status

session.s3.mobile boolean is populated by a quick check on the Browser in models/00_settings.py.

session.s3.browser Storage of capabilities is populated by a detailed check on the Browser in models/00_settings.py.

These can be used to direct to appropriate pages - e.g. assess/create goes to assess_short_mobile

the values to be populated in session.s3.browser has to be set in features (an instance of storage) in models/00_settings.py under definition of populate_browser_compatibility() function.

the complete listing of available features detected by pywurfl is as follows.
