Well it's not a "physical" redirect, its a replacement. The page does
nothing else than streaming an image back to the browser, tapestry
does not need to do a redirect for that.
I can't really tell you how well it performs in real life, it does
not have a big user base (maybe 200 users).
I have a project list with about 20 test projects. For each of those I
have a thumbnail in the list. The link for the <img> tag is generated
using the following line:
pageRenderLinkResources.createPageRenderLinkWithContext(ProjectThumbnailStream.class,
project.id);
The load statistic (checked with firebug) in my local test environment
tell me that a Asset Image loads in 62ms and the stream-page-images
load in 62-100ms. On a page refresh the numbers are even lower.
I would say reading the files from the file system and transferring
them over the networks are the biggest performance killer. I guess
since it's a shortcircuited page, it's faster than a normal page class
anyway.
The beauty of it is that I can use the tapestry context and all functions.
If you use static images, you also could
1. use a filter or
2. add the images to the app or
3. if you use a app-server behind an apache server, serve the images
directly through the apache.
in either case you need a method that figures out the correct link to
the images. Maybe in a mixin or a component.
