Create a proxy within the iOS app

By User



I have an app with an UIWebView (which is connected with a website); the user will navigate into the website. After that, I want that when the user open the app and there is no connection, the already visited pages will be accessible.





So I though that it should be possible if I create an internal proxy within the app: each request will be processed by this proxy (and will send the result to the UIWebView). Of course, the proxy should cache the web pages and, if there is no connection available, use the cached pages.





I prefer this approach instead of others (HTML5 offline cache) because, in the future, I will can set some feature to the proxy, for example "I want to cache all the pictures for the next 5 hours" etc...





Do you know if it's possible and, if it is, what should I use to do it? Or... do you know if there is something similar already done (some Objective-C Proxy?) ?

I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
