- * 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
