| /* |
| * BUGS: |
| * |
| * - uses strcpy/etc. |
| * - has various other poor buffer attacks related to the lazy parsing of |
| * response headers from the server |
| * - doesn't implement much of HTTP/1.x, only accepts certain forms of |
| * responses |
| * - (performance problem) heavy use of strstr shows up top in profile |
| * only an issue for loopback usage |
