30 | Revision 1.13 2000/01/25 22:46:54 sjboddie
|
---|
31 | changes to get fastcgi working properly
|
---|
32 |
|
---|
33 | Revision 1.12 1999/11/08 20:26:38 sjboddie
|
---|
34 | added multiplevalue option to cgiarginfo
|
---|
35 |
|
---|
36 | Revision 1.11 1999/11/01 22:03:35 sjboddie
|
---|
37 | Added ability to handle multiple arguments with the same name (as
|
---|
38 | is the case with multiple checkboxes using the same name). I'm not
|
---|
39 | sure this is the best way to do it but it does the trick for what
|
---|
40 | I currently need.
|
---|
41 |
|
---|
42 | Revision 1.10 1999/09/21 21:41:17 sjboddie
|
---|
43 | fixed a couple of problems in what I committed last
|
---|
44 |
|
---|
45 | Revision 1.9 1999/09/21 11:30:39 sjboddie
|
---|
46 | added ability to escape out '-' in saved args (currently
|
---|
47 | with a 'Z' ???)
|
---|
48 |
|
---|
49 | Revision 1.8 1999/09/07 04:56:53 sjboddie
|
---|
50 | added GPL notice
|
---|
51 |
|
---|
52 | Revision 1.7 1999/08/25 22:27:13 sjboddie
|
---|
53 | prevented cgi_safe from converting '+' and '-'. It was causing problems
|
---|
54 | with query strings containing spaces. The space was being converted
|
---|
55 | to '+', then %2b, then %xx2b over time when saved in compressed args.
|
---|
56 | I hope this won't cause problems elsewhere...
|
---|
57 |
|
---|
58 | Revision 1.6 1999/07/11 01:05:19 rjmcnab
|
---|
59 | Stored origin of cgiarg with argument.
|
---|
60 |
|
---|
61 | Revision 1.5 1999/06/26 01:08:36 rjmcnab
|
---|
62 | Added encoding and decoding of multibyte compresesd arguments.
|
---|
63 |
|
---|
64 | Revision 1.4 1999/06/08 22:03:43 sjboddie
|
---|
65 | query string is now made cgi safe before being added to compressed args
|
---|
66 |
|
---|
67 | Revision 1.3 1999/02/08 01:28:00 rjmcnab
|
---|
68 |
|
---|
69 | Got the receptionist producing something using the statusaction.
|
---|
70 |
|
---|
71 | Revision 1.2 1999/02/05 10:42:43 rjmcnab
|
---|
72 |
|
---|
73 | Continued working on receptionist
|
---|
74 |
|
---|
75 | Revision 1.1 1999/01/08 08:40:56 rjmcnab
|
---|
76 |
|
---|
77 | Moved from lib directory.
