ASP.NET 2.0 image caching

[Amelyan]

Is there a way to cache an image without having to cache the whole page
(aspx) or the whole control (ascx) where the image is located?

Thanks,

No answer from me.
I just want to know the answer too!

Hello Amelyan,

Is there a way to cache an image without having to cache the whole
page (aspx) or the whole control (ascx) where the image is located?

An image is not embedded in a control or page -- it's just a reference to
another file on the web sever which reqires another HTTP request to be fetched.
All you need to do is configure your web server to mark these files as cacheable,
if you find that this isn't the default behaviour or require more granular
control over your files' cacheability.

Cheers,

How can I mark my whole "Images" directory as cachable in IIS 6.0?

Hello Amelyan,

How can I mark my whole "Images" directory as cachable in IIS 6.0?

I don't have an IIS 6.0 available right now, but assuming it hasn't changed
since 5.x, you perform the following steps:

1. Run the IIS admin applet
2. Navigate to the image folder in the tree view
3. Open the folder's context menu and select Properties
4. Here, you can set an expiration date for all files contained in that folder.
You can also choose to set any other HTTP header, such as CacheControl: no-cache.

Hope that helps.

Cheers,
