12 | DESCRIPTION | |
13 | ----------- | |
14 | ||
15 | *sendfile* serves static files by sending them exactly as they are to | |
16 | clients. It needs to be called with the `X-Ash-File` header added to | |
1c273e0d | 17 | the request, as *dirplex*(1) does, unless the *-f* option is given. |

18 | |
19 | *sendfile* is a transient handler, as defined in *ashd*(7), and the | |
20 | 'METHOD', 'URL' and 'REST' arguments will normally be added by the | |
21 | parent handler. | |
22 | ||

23 | Normally, *sendfile* will serve the file named by the `X-Ash-File` |
24 | header, and fail with a 404 error in case the rest string is not | |
25 | empty. However, if the *-f* argument is given, the given 'FILE' will | |
26 | always be served instead, and the `X-Ash-File` header and any rest | |
27 | string is ignored. | |

29 | A file's MIME type may be specified explicitly either by using the |
30 | *-c* option, or by passing the header `X-Ash-Content-Type` to | |
31 | *sendfile* with the MIME type of the file. That header might, for | |
32 | instance, be set using the *set* directives of *dirplex*(1) or | |
33 | *patplex*(1). | |
34 | ||

35 | If a MIME-type is not explicitly specified, *sendfile* uses |
36 | *libmagic*(3) to determine the MIME-type automatically. If *sendfile* | |
37 | is compiled with support for filesystem attributes (see *attr*(5) if | |
38 | your system has support for such attributes), the attributes | |
39 | `user.ash-mime-type`, `user.mime-type`, `user.mime_type` or | |
40 | `user.Content-Type` will be checked, in that order, and if one is | |
41 | present on the file in question, its value will be used instead of | |
42 | using *libmagic*. | |

44 | *sendfile* supports the following HTTP features: |
45 | ||
46 | * Caching, using the `Last-Modified` and related headers. | |
47 | ||
48 | * Partial content, using the `Range` and related headers. | |

50 | OPTIONS | |
51 | ------- | |
52 | ||
53 | *-c* 'CONTENT-TYPE':: | |
54 | ||
55 | Sends 'CONTENT-TYPE' as the file's MIME-type instead of trying | |
56 | to auto-detect the file type. | |
57 | ||
1c273e0d FT |
58 | *-f* 'FILE':: |
59 | ||
60 | Ignore the `X-Ash-File` header and force 'FILE' to be served | |
61 | instead. Any remaining rest string is also ignored. | |
