345 * figuring out the content-type, by looking at the header (first
346 * few bytes) of the file. (like the file(1) command). We could
347 * also call the "file" command through Runtime. This is an
348 * option that I almost prefer as it is already implemented and
349 * exists with an up-to-date map on most modern Unix like systems.
350 * I haven't found a really nice implementation of the magic method
353 * The first method we try thought is the "Oreilly method". It
354 * relies on the content-type that the client browser sends and
355 * that sometimes is application-octet stream with
356 * broken/mis-configured browsers.
358 * The map file we use for the extensions is the standard web-app
359 * deployment descriptor file (web.xml). See Mir's web.xml or see
360 * your Servlet containers (most likely Tomcat) documentation.
