[lwip-users] [OT] httpd: download static files from an external HTTP server

[Giuseppe Modugno]

I think this isn't strictly related to lwip, but it's a request typical 
on electronic devices where lwip runs, i.e. devices with limited and 
restricted resources.

I have a limited non-volatile memory where to save html (and css, and 
images, and javascript, ...) files. Considering that the user will be 
always online (connected to Internet), I'm thinking to store some big 
static files (mainly images) on an external webserver.

I know it is perfectly possibile, but I'm trying to find a flexible way 
to do this. I'd like to have a single point in my files (maybe in a .js 
file) where to change this behaviour:

  var use_external_server = false;        // or true

Depending on this variable, the URI of some static files should be:

  /img/big_image.png

or

  external.webserver.org/img/big_image.png

Any suggestions?
