30 | Revision 1.30 1999/09/07 04:56:58 sjboddie
|
---|
31 | added GPL notice
|
---|
32 |
|
---|
33 | Revision 1.29 1999/09/03 10:02:30 rjmcnab
|
---|
34 | Made the page parameters configurable. Now the page parameters must
|
---|
35 | correspond to cgi arguments in name and value (ie language=zh should now
|
---|
36 | be l=zh) which makes things more consistent anyway. Removed a couple of
|
---|
37 | specialised NZDL page parameters.
|
---|
38 |
|
---|
39 | Moved the combining of the cgi arguments so that the receptionist does
|
---|
40 | all the configuration now.
|
---|
41 |
|
---|
42 | Made the macro precedence configurable.
|
---|
43 |
|
---|
44 | Made cgi arguments totally configurable. Now any piece of information about
|
---|
45 | a cgi argument can be configured meaning that cgi arguments can be declared
|
---|
46 | from the configuration file.
|
---|
47 |
|
---|
48 | Removed the argdefault configuration argument. This should now be done
|
---|
49 | using cgiarg.
|
---|
50 |
|
---|
51 | Revision 1.28 1999/09/03 04:39:46 rjmcnab
|
---|
52 | Made cookies and logs optional (they are turned off by default). To
|
---|
53 | turn them on put
|
---|
54 |
|
---|
55 | usecookies true
|
---|
56 | logcgiargs true
|
---|
57 |
|
---|
58 | in your configuration file.
|
---|
59 |
|
---|
60 | Revision 1.27 1999/09/02 00:27:21 rjmcnab
|
---|
61 | A few small things.
|
---|
62 |
|
---|
63 | Revision 1.26 1999/08/25 04:43:06 sjboddie
|
---|
64 | made FilterRequest_t::docSet an array rather than a set
|
---|
65 |
|
---|
66 | Revision 1.25 1999/08/20 00:59:01 sjboddie
|
---|
67 | -fixed up location redirection
|
---|
68 | -added some usage logging, also now set a GSDL_UID cookie. Logging
|
---|
69 | does NOT presently lock the log file while it's in use. That has yet
|
---|
70 | to be done.
|
---|
71 |
|
---|
72 | Revision 1.24 1999/08/13 04:16:42 sjboddie
|
---|
73 | added some collection-level metadata stuff
|
---|
74 |
|
---|
75 | Revision 1.23 1999/08/11 23:28:59 sjboddie
|
---|
76 | added support for html classifier (i.e. the hp argumant now must be
|
---|
77 | translated too).
|
---|
78 |
|
---|
79 | Revision 1.22 1999/08/10 22:45:21 sjboddie
|
---|
80 | format option ShowTopPages is now called DocumentTopPages
|
---|
81 |
|
---|
82 | Revision 1.21 1999/08/09 04:25:17 sjboddie
|
---|
83 | moved OID translation stuff from documentaction::define_external_macros
|
---|
84 | to receptionist
|
---|
85 |
|
---|
86 | Revision 1.20 1999/07/30 02:13:09 sjboddie
|
---|
87 | -added collectinfo argument to some functions
|
---|
88 | -made some function prototypes virtual
|
---|
89 |
|
---|
90 | Revision 1.19 1999/07/15 06:02:05 rjmcnab
|
---|
91 | Moved the setting of argsinfo into the constructor. Added the configuration
|
---|
92 | command argdefault (as used by the actions). Added code to output the
|
---|
93 | correct charset based on the page encoding so that the user does not need
|
---|
94 | to specify the encoding used for a particular page.
|
---|
95 |
|
---|
96 | Revision 1.18 1999/07/11 01:05:20 rjmcnab
|
---|
97 | Stored origin of cgiarg with argument.
|
---|
98 |
|
---|
99 | Revision 1.17 1999/07/10 22:18:26 rjmcnab
|
---|
100 | Added calls to define_external_cgiargs.
|
---|
101 |
|
---|
102 | Revision 1.16 1999/06/27 21:49:03 sjboddie
|
---|
103 | fixed a couple of version conflicts - tidied up some small things
|
---|
104 |
|
---|
105 | Revision 1.15 1999/06/26 01:14:32 rjmcnab
|
---|
106 | Made a couple of changes to handle different encodings.
|
---|
107 |
|
---|
108 | Revision 1.14 1999/06/09 00:08:36 sjboddie
|
---|
109 | query string macro (_cgiargq_) is now made html safe before being set
|
---|
110 |
|
---|
111 | Revision 1.13 1999/06/08 04:29:31 sjboddie
|
---|
112 | added argsinfo to the call to check_cgiargs to make it easy to set
|
---|
113 | args to their default if they're found to be screwed up
|
---|
114 |
|
---|
115 | Revision 1.12 1999/04/30 01:59:42 sjboddie
|
---|
116 | lots of stuff - getting documentaction working (documentaction replaces
|
---|
117 | old browseaction)
|
---|
118 |
|
---|
119 | Revision 1.11 1999/03/25 03:06:43 sjboddie
|
---|
120 |
|
---|
121 | altered receptionist slightly so it now passes *collectproto to
|
---|
122 | define_internal_macros and define_external_macros - need it
|
---|
123 | for browseaction
|
---|
124 |
|
---|
