281 * This is a way to get the content-type via the .extension,
282 * we could maybe use a magic method as an additional method of
283 * figuring out the content-type, by looking at the header (first
284 * few bytes) of the file. (like the file(1) command). We could
285 * also call the "file" command through Runtime. This is an
286 * option that I almost prefer as it is already implemented and
287 * exists with an up-to-date map on most modern Unix like systems.
288 * I haven't found a really nice implementation of the magic method
291 * The first method we try thought is the "Oreilly method". It
292 * relies on the content-type that the client browser sends and
293 * that sometimes is application-octet stream with
294 * broken/mis-configured browsers.
296 * The map file we use for the extensions is the standard web-app
297 * deployment descriptor file (web.xml). See Mir's web.xml or see
298 * your Servlet containers (most likely Tomcat) documentation.
299 * So if you support a new media type you have to make sure that
