Hi

Does anyone have experience using gZip compression on the IIS server with a
ASP.NET application. How much can a page be compressed. As i see it it must
have a huge impact on the total size. Eg. if i take a 400 kb (260 rows in a
datagrid with viewstate) and saveit as txt file an compress it with winzip i
zipped to around 30 kb. Thats something! Is the compression rate in the same
area on the IIS server?

Is there any penalties expect a higher CPU usage from the IIS server? (No
problem in our application) Pther problem that i should be aware of?

Thank in regards
Anders Jacobsen

No. It just rocks. But just a little system admins configure IIS with
compression. A big pity...
Expect compression up to 90%

From what I've experienced in web applications, expect compression rated of
at least 70%.

For high traffic sites, you can perform compression through specialized
hardware like Redline T|X boxes.

compression?

At least all modern versions of IE, Mozilla/Firefox, and Opera (don't know
about Safari, but HTTP compression has been around for years now) . HTTP
compression is only applied if the user agent sends an appropriate
"Accept-Encoding" header, so even older browsers will continue to work, but
recieve uncompressed content.
