Caching ASHX Image Response

Question

I have created an ashx file to generate image thumbnails on the fly. I would like to cache these images client side after they are called the first time.

URL:

<

Answer 1

Surely this line:

HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Server);

Should be:

HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);
