| * "Content-Type: text/plain\015\012". Now all the characters in the string |
| * are stored as EBCDIC, only the semantics of \012 is completely |
| * different from LF (look it up in the apr_table_t above). \015 happens to be |
| * mapped to \015 anyway, so there's no special case for it. |
| * |
| * In THIS table, EBCDIC-\012 is mapped to ASCII-\012. |
| * This apr_table_t is therefore used wherever an EBCDIC to ASCII conversion is |
| * needed in the server. |
