Glenn L McGrath | 06e9565 | 2003-02-09 06:51:14 +0000 | [diff] [blame] | 14 | * Typical usage: |
| 15 | * for non root user |
| 16 | * httpd -p 8080 -h $HOME/public_html |
| 17 | * or for daemon start from rc script with uid=0: |
| 18 | * httpd -u www |
| 19 | * This is equivalent if www user have uid=80 to |

| 23 | * When a url contains "cgi-bin" it is assumed to be a cgi script. The |
| 24 | * server changes directory to the location of the script and executes it |
Glenn L McGrath | 1dc0cca | 2003-10-03 10:50:56 +0000 | [diff] [blame] | 25 | * after setting QUERY_STRING and other environment variables. |

| 31 | * as follows: |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 32 | * foo=`httpd -d $foo` # decode "Hello%20World" as "Hello World" |

Eric Andersen | aff114c | 2004-04-14 17:51:38 +0000 | [diff] [blame] | 35 | * presentation. -d decodes a url-encoded argument while -e encodes in html |

Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 55 | * The Deny/Allow IP logic: |
Eric Andersen | c7bda1c | 2004-03-15 08:29:22 +0000 | [diff] [blame] | 56 | * |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 57 | * - Default is to allow all. No addresses are denied unless |
Eric Andersen | 97a1de1 | 2004-08-26 22:22:50 +0000 | [diff] [blame] | 58 | * denied with a D: rule. |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 59 | * - Order of Deny/Allow rules is significant |
| 60 | * - Deny rules take precedence over allow rules. |
| 61 | * - If a deny all rule (D:*) is used it acts as a catch-all for unmatched |
Eric Andersen | 97a1de1 | 2004-08-26 22:22:50 +0000 | [diff] [blame] | 62 | * addresses. |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 63 | * - Specification of Allow all (A:*) is a no-op |
Eric Andersen | c7bda1c | 2004-03-15 08:29:22 +0000 | [diff] [blame] | 64 | * |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 65 | * Example: |

| 70 | * D:* # Deny from other IP connections |
Eric Andersen | c7bda1c | 2004-03-15 08:29:22 +0000 | [diff] [blame] | 71 | * |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 72 | * 2. Only deny specified addresses |
| 73 | * D:1.2.3. # deny from 1.2.3.0 - 1.2.3.255 |

Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 77 | * If a sub directory contains a config file it is parsed and merged with |
Glenn L McGrath | b65422c | 2003-09-08 10:59:27 +0000 | [diff] [blame] | 78 | * any existing settings as if it was appended to the original configuration. |
Glenn L McGrath | 4fe3ff8 | 2003-05-19 05:56:16 +0000 | [diff] [blame] | 79 | * |
| 80 | * subdir paths are relative to the containing subdir and thus cannot |
| 81 | * affect the parent rules. |
| 82 | * |
| 83 | * Note that since the sub dir is parsed in the forked thread servicing the |
| 84 | * subdir http request, any merge is discarded when the process exits. As a |
| 85 | * result, the subdir settings only have a lifetime of a single request. |

| 704 | * $Description: Given a URL encoded string, convert it to plain ascii. |

| 706 | * Thus, callers should strdup() the argument if they do not want the |
| 707 | * argument modified. The return is the original pointer, allowing this |
| 708 | * function to be easily used as arguments to other functions. |
| 709 | * |
| 710 | * $Parameters: |
| 711 | * (char *) string . . . The first string to decode. |
