<!–#### SECURITY Related Headers ###
More information: https://www.owasp.org/index.php/List_of_useful_HTTP_headers
–>
<!–
# Access-Control-Allow-Origin
The ‘Access Control Allow Origin’ HTTP header is used to control which
sites are allowed to bypass same origin policies and send cross-origin requests.

Secure configuration: Either do not set this header, or return the ‘Access-Control-Allow-Origin’
header restricting it to only a trusted set of sites.
http://enable-cors.org/

<add name=”Access-Control-Allow-Origin” value=”*” />
–>

<!–
# Cache-Control
The ‘Cache-Control’ response header controls how pages can be cached
either by proxies or the users browser.
This response header can provide enhanced privacy by not caching
sensitive pages in the users browser cache.

<add name=”Cache-Control” value=”no-store, no-cache”/>
–>

<!–
# Strict-Transport-Security
The HTTP Strict Transport Security header is used to control
if the browser is allowed to only access a site over a secure connection
and how long to remember the server response for, forcing continued usage.
Note* Currently a draft standard which only Firefox and Chrome support. But is supported by sites like PayPal.
<add name=”Strict-Transport-Security” value=”max-age=15768000″/>
–>

<!–
# X-Frame-Options
The X-Frame-Options header indicates whether a browser should be allowed
to render a page within a frame or iframe.
The valid options are DENY (deny allowing the page to exist in a frame)
or SAMEORIGIN (allow framing but only from the originating host)
Without this option set the site is at a higher risk of click-jacking.

<add name=”X-Frame-Options” value=”SAMEORIGIN” />
–>

<!–
# X-XSS-Protection
The X-XSS-Protection header is used by Internet Explorer version 8+
The header instructs IE to enable its inbuilt anti-cross-site scripting filter.
If enabled, without ‘mode=block’, there is an increased risk that
otherwise non-exploitable cross-site scripting vulnerabilities may potentially become exploitable

<add name=”X-XSS-Protection” value=”1; mode=block”/>
–>

<!–
# MIME type sniffing security protection
Enabled by default as there are very few edge cases where you wouldn’t want this enabled.
Theres additional reading below; but the tldr, it reduces the ability of the browser (mostly IE)
being tricked into facilitating driveby attacks.

http://blogs.msdn.com/b/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx
–>
<add name=”X-Content-Type-Options” value=”nosniff” />

<!– A little extra security (by obscurity), removings fun but adding your own is better –>
<remove name=”X-Powered-By” />
<add name=”X-Powered-By” value=”My Little Pony” />

# E-TAGS
E-Tags are actually quite useful in cache management especially if you have a front-end caching server
such as Varnish. http://en.wikipedia.org/wiki/HTTP_ETag / http://developer.yahoo.com/performance/rules.html#etags
But in load balancing and simply most cases ETags are mishandled in IIS; and it can be advantageous to remove them.
This is simply done by overriding the default server header with an empty tag.
See http://bytestopshere.wordpress.com/2009/02/02/disable-remove-etags-on-iis-6-to-improve-performance/

<add name=”ETAG” value=”” />

Force the latest IE version, in various cases when it may fall back to IE7 mode
github.com/rails/rails/commit/123eb25#commitcomment-118920
Use ChromeFrame if it’s installed for a better experience for the poor IE folk
–>
<add name=”X-UA-Compatible” value=”IE=Edge,chrome=1″ />
<!–
Allow cookies to be set from iframes (for IE only)
If needed, uncomment and specify a path or regex in the Location directive

<rewrite>
<rules>

Remove/force the WWW from the URL.
Requires IIS Rewrite module http://learn.iis.net/page.aspx/460/using-the-url-rewrite-module/
Configuration lifted from http://nayyeri.net/remove-www-prefix-from-urls-with-url-rewrite-module-for-iis-7-0

NOTE* You need to install the IIS URL Rewriting extension (Install via the Web Platform Installer)
http://www.microsoft.com/web/downloads/platform.aspx

** Important Note
using a non-www version of a webpage will set cookies for the whole domain making cookieless domains
(eg. fast cdn-like access of static resources like css, js and images) impossible.

# IMPORTANT: THERE ARE TWO RULES LISTED. NEVER USE BOTH RULES AT THE SAME TIME!

<rule name=”Remove WWW” stopProcessing=”true”>
<match url=”^(.*)$” />
<conditions>
<add input=”{HTTP_HOST}” pattern=”^(www\.)(.*)$” />
</conditions>
<action type=”Redirect” url=”http://example.com{PATH_INFO}” redirectType=”Permanent” />
</rule>
<rule name=”Force WWW” stopProcessing=”true”>
<match url=”.*” />
<conditions>
<add input=”{HTTP_HOST}” pattern=”^example.com$” />
</conditions>
<action type=”Redirect” url=”http://www.example.com/{R:0}” redirectType=”Permanent” />
</rule>

### Built-in filename-based cache busting

In a managed language such as .net you should really be using the internal bundler for css + js
or getCassette or similar.

If you’re not using the build script to manage your filename version revving,
you might want to consider enabling this, which will route requests for
/css/style.20110203.css to /css/style.css

To understand why this is important and a better idea than all.css?v1231,
read: github.com/h5bp/html5-boilerplate/wiki/Version-Control-with-Cachebusting

<rule name=”Cachebusting”>
<match url=”^(.+)\.\d+(\.(js|css|png|jpg|gif)$)” />
<action type=”Rewrite” url=”{R:1}{R:2}” />
</rule>

</rules>
</rewrite>–>

</system.webServer>
</configuration>

———————————————————————————

You can customize as per your requirement cache time limit ,and now you question,

What is gzip compression?

When a user hits your website a call is made to your server to deliver the requested files.

The bigger these files are the longer it’s going to take for them to get to your browser and appear on the screen.

Gzip compresses your webpages and style sheets before sending them over to the browser. This drastically reduces transfer time since the files are much smaller.

What is Caching?

Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results.

In the case of websites, the browser can save a copy of images, style-sheets, JavaScript or the entire page. The next time the user needs that resource (such as a script or logo that appears on every page), the browser doesn’t have to download it again. Fewer downloads means a faster, happier site.
