Method: WebTranslateIt::TranslationFile#fetch

Defined in:
lib/web_translate_it/translation_file.rb

#fetch(http_connection, force = false) ⇒ Object

Fetch a language file. By default it will make a conditional GET Request, using the ‘If-Modified-Since` tag. You can force the method to re-download your file by passing `true` as a second argument

Example of implementation:

configuration = WebTranslateIt::Configuration.new
file = configuration.files.first
file.fetch # the first time, will return the content of the language file with a status 200 OK
file.fetch # returns nothing, with a status 304 Not Modified
file.fetch(true) # force to re-download the file, will return the content of the file with a 200 OK
