> I am using the RESTFul plugin and this exception is thrown when I visit the page enabled *Caching*.
> When I trigger an action from my web browser, it pass the *If-Modified-Since* attribute to server side and the locale of it date format is in *en* - *Wed, 18 Dec 2013 16:00:00 GMT*.
> Then, in the server side, the *DefaultHttpHeaders* uses the method *compareIfModifiedSince()* to check if it should return the cached data. However, I found that the *DefaultHttpHeaders.compareIfModifiedSince()* would use the *default locale* of the server for parsing the *If-Modified-Since* input which causes ParseException as the locale of the server is NOT same as the web browser I used.
