HTTP compression

IIS 6 has HTTP compression built in and other 3rd party tools like IIS
Accelerator add the same functionality to IIS 5 and IIS 4. IIS Accelerator
works great giving us 80% compression of some pages.

The question is, does this compression apply to included JavaScript:

<script language="javascript" src="PeopleScreen.js"></script>

Will that PeopleScreen.js file get compressed as well?

Thanks, Rob.

Not per default (default is *.htm, *.html and *.txt only AFAIK).
You can add extensions (for example *.js, *.css, *. aspx) manually via
metabase:

Or you let a tool do this for you, I use ZipEnable:

you can configure your settings within the 30 day trial, so you don't have
to buy ;o)

Oh, you use IIS5!?
Then for built-in compression you have to do this:
http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/iis/maintain/featusability/httpcomp.mspx

If you are not firm using cscript.exe then you can use MetaEdit instead
(like Regedit):

If you are using a third party tool, then ask them.

With IIS6, there are two types of compression "schemes" (static and dynamic)
that can be applied to any URL extension served by IIS. So you enable static
compression on .js extension, then if the browser makes a request for .js
URL and indicates that it supports compression, IIS will send it as
compressed.

By default, IIS6 comes with compression turned off and defined for a small
set of URLs (basically .htm, .html, .txt, .asp, .dll, .exe). You can of
course choose the applicable extensions as well as static/dynamic scheme and
the compression algorithm.

Hi Rob,

For the configuration of Http compression, the metabase.xml file is located
at %windir%\system32\inetsrv\metabase.xml. The IIsCompressionSchemes and
IIsCompressionScheme contain the configurtion information on HTTP
compression.
*Please backup this file before editting in case any error to down the
server.

Please feel free to let me know if any question. My pleasure to be of any
assistance.

Oh, didn't realise IIS5 had HTTP compression as well - thought it was a IIS6
new feature.
