How to adress to "Make javascript and css extrnal" issue form yslow?

The Expires headers : Can you explain how does it work? Will I have to change it every in a  in a while? I'm sorry but I don't get it. and I need to set it in the header.php file where exctly? Isnt the w3 total cache is suppose to set it up already?

and How can I set an expiration date for pages I didnt create such as http://www.google-analytics.com/ga.js?

I do need to apologize, the expires header I listed was actually for a "no-cache" situation on a site.  What you want are called "Far Future" expires headers.  If you have an Apache server you could add another directive as follows:

header('ExpiresDefault "access plus 10 years"');

other than that just set the header to expire in some future far date:

header("Expires: Wed, 26 Jul 2017 05:00:00 GMT");

In this case you would have to change the date again as you get close (say within one year) of the expires date, although in WordPress that isn't that hard.  Your headers normally are located in only one place.

Obviously, expires headers only apply to elements that you control.  There are only so many things you can do to speed up your site.

The Far Future expires header does the oposite of the "No-Cache" header in that it gives permission to your browser to cache this page for faster loading.

Its a shared  host so I don't think I can add it to the server.
but again Isnt the w3 total cache is suppose to set it up already?

I don't understand it how does it help the speed if Im setting an header to expire in one year how does it help to cache the page ? if you have a good refresher that would be great

how can I  Specify an expiration for an Img ?

I'm sorry, I am not familiar with w3 cache's operation, but your YSlow should detect whether it does handle the far future expires or not.

Having a shared host makes no difference as far as far future headers are concerned.  This is a browser command, not a server command.

Basically, the far future header tells the browser that the page that it has in memory can still be used because the expiration date has not arrived as of yet.  Once the date arrives, the browser goes back to the server and loads a new version of the page.  So, by saving trips to the server, your website speeds up.

You can read more about this at http://cjohansen.no/en/apache/using_a_far_future_expires_header

Far future expiries are for web pages, not specific elements on the page.

I keep getting the message from page speed

The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:

and than for example I get
newspaper-icon.png

How can I set an expiration to One img?

Oh, sorry.  I misunderstood.

Try adding the following to the .htaccess file of your server:

ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/jpeg A2592000

I do see in my  .htacess the same lines but with A31536000
so to replace it ?

If that's the case, I don't understand your error.  Are you sure the .htaccess specifies image/png?

try to run http://www.chicagonewshub.com/ill-lawmakers-react-to-nations-credit-downgrade/
in page speed and you will see it.

Just a side note, you have a syntax error in your w3 cache javascript file: http://www.chicagonewshub.com/wp-content/w3tc/min/dd2454aa.94d4ff.js on line

page speed shows the following:
 
From what I am seeing, your site is scoring 88 out of 100.  You will never get 100 with all the content that you have.

IMHO, you are doing pretty good already.

I didnt change anything in their script so what should I do?

Its not doing good I just stop the images for a while to test it  actully  pretty low take a look again on
http://www.chicagonewshub.com/

OK, now I see it.  The Apache mod_expires are set.  This should not be happening.  I would submit a trouble ticket to your host.

I did they said they r not dealing with that  issues.

Can you attach a copy of your .htaccess file for me to look at?

The code looks fine.  You should ask your host to verify access to the mod_expires.c file.

they are saying that That file is enabled on the server

You should tell them that you have the following in the .htaccess file:

<IfModule mod_mime.c>
    AddType image/png .png
</IfModule>
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/png A31536000

yep I used it also but I still don't get why some objects not getting expired headers and some objects doesnt get minify even the I configured w3 total cache to that options
