I have a simple controller that loads an image off the disk, re sizes
it and outputs it to the response stream:
[Cache(HttpCacheability.Public, ValidUntilExpires = true, Duration =
60*60, VaryByHeaders = "x-castle-route")]
public void ViewLocal(string path, double? maxWidth, double?
maxHeight)
{
Context.Request.Headers.Add("x-castle-route",
Context.UrlInfo.UrlRaw);
byte[] data = File.ReadAllBytes(Context.Server.MapPath(path));
OutputImage(data, maxHeight, maxWidth); // resizes with the bilinear
algorithm and outputs
}
Unfortunately I can no longer use made up headers in my environment
(rackspace cloud's medium trust rules). I don't use VaryByParams
because I use the routing engine. I think I can get this done with
ETags, but I can't find anything on the net about Castle/MonoRail and
etags. Can someone point me in the right direction? Thanks!
