| * This module is intended to be used for testing chunked encoding. It |
| * generates a whole whack of output using ap_bputc() and ap_bputs(). It |
| * also exercises start_chunk() and end_chunk() in buff.c. To use it |
| * you should use a tool like netcat and the src/test/check_chunked |
| * tool. Add something like this to your access.conf file: |
| * |
| * <Location /rndchunk> |
| * SetHandler rndchunk |
| * </Location> |
| * |
| * Then fake requests such as: |
| * |
| * GET /rndchunk?0,1000000 HTTP/1.1 |
| * Host: localhost |
| * |
| * The first arg is the random seed, the second is the number of |
| * "things" to do. You should try a few seeds. |
| * |
| * You should also edit main/buff.c and change DEFAULT_BUFSIZE (and |
| * CHUNK_HEADER_SIZE). Small values are particularly useful for |
| * finding bugs. Try a few different values. |
| * |
