<div>Please correct me if I am wrong, but this still serves the files through the image, only now you are imposing the overhead of first reading the file from the hard drive. This will slow things down, not speed them up, but perhaps your aim is to conserve RAM used by the image? (But of course, loading the files into the image will temporarily increase in-memory image size, and since every request will create load its own set of files from the hard drive, this could drive memory usage way up depending on how many requests are being served.</div>
<div>Am I interpreting this correctly?</div>

<div><br></div>
<div>I have JQuery CSS files that reference a large number of image files from an images subdirectory. When these files are imported into a WAFileLibrary, the image filenames are changed and of course there are no subdirectories. Changing the original css file to accommodate this is not practical as I expect to receive new ones periodically and then would have to do it all over again.</div>
<div><br></div>
<div>I am attracted by the easy deployment of Seaside apps when Apache is not involved and for the few files involved it doesn't seem to me that Apache is warranted, especially during development of the site.</div>
<div><br></div>
<div>I could find no information on the right way to do this, so I subclassed WAServerAdaptor as shown below.</div>
<div><br></div>
<div>With these modifications, If the URL received from the browser's path begins with /static, then files are served from a specified directory. Otherwise, the request is passed on (eventually) to WADispatcher as normal.</div>
<div><br></div>
<div>This works for me, but I have no idea as to whether there is an easier or better way or if there is a feature to allow this that I just did not find.</div>
<div><br></div>
<div>I am coming back to Smalltalk after many years and I am definitely a bit rusty, so any criticism of the code will also be greatly appreciated.</div>
