In ASP.NET can I cache a <body>'s background image?

Hi. I'm building an ASP.NET 2.0 web-app for a customer. The customer wants
a background image that's 124k in size as the background for each page. I've
recommended they use a smaller-size image, but the customer is absolutely
adamant about using the image.

I'm afraid that this large image will degrade performance if it's loaded for
each page. Can I somehow use ASP.NET caching to cache the background image
so it doesn't have to refresh on each page load?

Thanks, Mike

Set a custom header, which specifies "max-age".

Open the IIS Manager snap-in from Administrative Tools, pick an app,
right click, go to Properties, switch to the HTTP Headers tab, and click Add.

Add cache-control extensions like this:

In the "Custom Header Name", type : Cache-Control

In the Custom Header Value, type :

"Cache-Control:max-age=NumberOfSeconds"

OK your way out of the dialog...

I use :
"Cache-Control:max-age=1200"
....which will cache images for the default session timout ( 20 minutes ).

Mike, you can also write a custom HttpHandler and map images to the
ASP.NET ISAPI in IIS. And then from ASP.NET you will be able to add
cache contol values, the same what Juan told you

Response.Cache.AppendCacheExtension("max-age=NumberOfSeconds");

I would also recommend you to check:

Thank you both for your help!

Easiest way ... CSS file

-------------------------------------------------------------
body { background-image: url( 'images/massivepic.jpg' ); }
-------------------------------------------------------------

Browsers will cache background images.
