HTML Cache External Images Only
Posted on 2012-12-25
In process of trying to optimize http://www.dealer24x7.com/Used/1/Inventory/ the recommendation we are getting from google's page speed insights (https://developers.google.com/speed/pagespeed/insights) is to leverage caching.
What meta tag do we need to use to specify caching images (local and external) longer (say 3 months) and caching the HTML of the page for only a week?
p.s.
The goal is to leverage public cache pools by using
<META HTTP-EQUIV="CACHE-CONTROL"

It's not a META tag.
Its a server Issue or setting
If you use IIS

Unfortunately some (or even a good majority) of the images come from third party servers that I have no control over
Active today
Image files don't have META tags or any other HTML in them. That would have to be done on the server. Here's a page about doing in Apache: http://www.chicagostyleseo.com/2010/04/googles-need-for-speed-use-cache-and-htaccess-to-speed-up-your-site/ I don't know how to set this up in IIS. I that in the other comment.
If they're from third party servers, there is nothing you can do about it.

So is there an HTML tag on the HTML page that I can use to say cache this page and its contents (local and external images) for 7 days?
Depending on your need to do this.
I'll just put this out here.
I have used this in the past.
What is does is takes an external Image and makes it local..
(FOR JPG's)
Create this page on your server in the root DIR and Name it extimage.php
NO Spaces BEFORE this.
Link to it like so
To add it into HTML would be like
<img src="http://www.dealer24x7.com/extimage.php?url=IMAGE PATH TO EXTERNAL JPG HERE">
