[Seaside] Serving files from within Seaside

[Diego Lont]

Hi Joachim,

Looking into WAFileLibrary and WAFileHandler won't help a lot: you get easily lost. They are great for serving static files, and do some buffering and such.

In Seaside 3.x the answer is more simple. Your code looks fine, the method you want to make looks something like:

calculateChartAndServeIt
	self requestContext respond: [ :response |
		response
			doNotCache;
			document: self calculateChart ]
