Hi All <br />
<br />
I was wondering if you could help me, I have been looking at page speed insights on google for my site and one of the issues was ‘Leverage browser caching’ My web designer said to resolve this would be to change IIS by setting HTTP Response Headers &gt;&nbsp;Set Common Headers &gt;&nbsp;Expire content (after 7 days). &nbsp;The issue I then have is that my site is hosted in a shared environment with Rackspace and I don't have access to IIS, I asked them the question and they told me I can just add some code to my webconfig file! &nbsp;<br />
<br />
I am know confused and wanted to know what I could do to improve my Page speed Insight, if you could help that would be appreciated. Thanks <br />
Alex

Hi All 

I was wondering if you could help me, I have been looking at page speed insights on google for my site and one of the issues was ‘Leverage browser caching’ My web designer said to resolve this would be to change IIS by setting HTTP Response Headers > Set Common Headers > Expire content (after 7 days).  The issue I then have is that my site is hosted in a shared environment with Rackspace and I don't have access to IIS, I asked them the question and they told me I can just add some code to my webconfig file!

Pagespeed Insights - ‘Leverage browser caching’

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
