ssi - server-side-includes CGI program |

.SH SYNOPSIS |

.SH DESCRIPTION |
| 7 |
.PP |
| 8 |
This is an external CGI program that gives you the same functionality |
| 9 |
as the built-in server-side-includes feature in some HTTP daemons. |
| 10 |
It is written for use with thttpd(8), but should be easy to adapt |
| 11 |
to other systems. |
| 12 |
.PP |
| 13 |
To use this program, first make sure it is installed in your server's |
| 14 |
CGI area, and that CGI is enabled. |
| 15 |
Then set up your URLs with the path to the document you want parsed |
| 16 |
as the "pathinfo". |
| 17 |
That's the part of the URL that comes after the CGI program name. |
| 18 |
For example, if the URL to this program is: |
| 19 |
.nf |
| 20 |
http://www.acme.com/cgi-bin/ssi |
| 21 |
.fi |
| 22 |
and the url for your document is: |
| 23 |
.nf |
| 24 |
http://www.acme.com/users/wecoyote/doc.html |
| 25 |
.fi |
| 26 |
then the compound URL that gives you the document filtered through the |
| 27 |
program would be: |
| 28 |
.nf |
| 29 |
http://www.acme.com/cgi-bin/ssi/users/wecoyote/doc.html |
| 30 |
.fi |
| 31 |
.PP |
| 32 |
The format description below is adapted from |
| 33 |
http://hoohoo.ncsa.uiuc.edu/docs/tutorials/includes.html |
| 34 |
.SH "INCLUDE FORMAT" |
| 35 |
.PP |
| 36 |
All directives are formatted as SGML comments within the document. |
| 37 |
This is in case the document should ever find itself in the client's |
| 38 |
hands unparsed. |
| 39 |
Each directive has the following format: |
| 40 |
.nf |
| 41 |
<!--#command tag1="value1" tag2="value2" --> |
| 42 |
.fi |
| 43 |
Each command takes different arguments, most only accept one tag at a time. |
| 44 |
Here is a breakdown of the commands and their associated tags: |
| 45 |
.IP * 4 |
| 46 |
.BR config : |
| 47 |
The config directive controls various aspects of the file parsing. |
| 48 |
There are two valid tags: |
| 49 |
.IP o 8 |
| 50 |
.BR timefmt : |
| 51 |
gives the server a new format to use when providing dates. |
| 52 |
This is a string compatible with the strftime library call. |
| 53 |
.IP o 8 |
| 54 |
.BR sizefmt : |
| 55 |
determines the formatting to be used when displaying the |
| 56 |
size of a file. |
| 57 |
Valid choices are bytes, for a formatted byte count |
| 58 |
(formatted as 1,234,567), or abbrev for an abbreviated version |
| 59 |
displaying the number of kilobytes or megabytes the file occupies. |
| 60 |
.IP * 4 |
| 61 |
.BR include : |
| 62 |
Inserts the text of another document into the parsed document. |
| 63 |
The inserted file is parsed recursively, so it can contain |
| 64 |
server-side-include directives too. |
| 65 |
This command accepts two tags: |
| 66 |
.IP o 8 |
| 67 |
.BR virtual : |
| 68 |
Gives a virtual path to a document on the server. |
| 69 |
.IP o 8 |
| 70 |
.BR file : |
| 71 |
Gives a pathname relative to the current directory. ../ cannot |
| 72 |
be used in this pathname, nor can absolute paths be used. |
| 73 |
.IP * 4 |
| 74 |
.BR echo : |
| 75 |
Prints the value of one of the include variables (defined below). |
| 76 |
Any dates are printed subject to the currently configured timefmt. |
| 77 |
The only valid tag to this command is var, whose value is the name of the |
| 78 |
variable you wish to echo. |
| 79 |
.IP * 4 |
| 80 |
.BR fsize : |
| 81 |
prints the size of the specified file, |
| 82 |
subject to the sizefmt parameter to the config command. |
| 83 |
Valid tags are the same as with the include command. |
| 84 |
.IP * 4 |
| 85 |
.BR flastmod : |
| 86 |
prints the last modification date of the specified file, subject |
| 87 |
to the formatting preference given by the timefmt parameter to config. |
| 88 |
Valid tags are the same as with the include command. |
| 89 |
.SH VARIABLES |
| 90 |
.PP |
| 91 |
A number of variables are made available to parsed documents. |
| 92 |
In addition to |
| 93 |
the CGI variable set, the following variables are made available: |
| 94 |
.IP * 4 |
| 95 |
.BR DOCUMENT_NAME : |
| 96 |
The current filename. |
| 97 |
.IP * 4 |
| 98 |
.BR DOCUMENT_URI : |
| 99 |
The virtual path to this document (such as /~robm/foo.shtml). |
| 100 |
.IP * 4 |
| 101 |
.BR QUERY_STRING_UNESCAPED : |
| 102 |
The unescaped version of any search query the client sent. |
| 103 |
.IP * 4 |
| 104 |
.BR DATE_LOCAL : |
| 105 |
The current date, local time zone. |
| 106 |
Subject to the timefmt parameter to the config command. |
| 107 |
.IP * 4 |
| 108 |
.BR DATE_GMT : |
| 109 |
Same as DATE_LOCAL but in Greenwich mean time. |
| 110 |
.IP * 4 |
| 111 |
.BR LAST_MODIFIED : |
| 112 |
The last modification date of the current document. |
| 113 |
Subject to timefmt like the others. |
| 114 |
.SH "BUGS / DEFICIENCIES" |
| 115 |
.PP |
| 116 |
Does not implement the "exec" directive. |
| 117 |
Actually, I consider this neither a bug nor a deficiency, but some may. |
| 118 |
.SH "SEE ALSO" |
