RE: proxy authentication.

I haven't really played with proxies yet, but the proxy flag in the
'Basic' authentication structure should do the trick. I didn't want
interactive authentication and I did the following:

// Declaration and constructor for authentication information.
typedef struct _MYBasic {		  /* Basic challenge and
credentials */
  char *	uid;
  char *	pw;
  BOOL	retry;			    /* Should we ask the user again? */
  BOOL	proxy;			    /* Proxy authentication */
} MYBasic;

PRIVATE MYBasic * MYBasic_new(char * username, char* password)
{
  MYBasic * me = NULL;
  if ((me = (MYBasic *) HT_CALLOC(1, sizeof(MYBasic))) == NULL)
    HT_OUTOFMEM("MYBasic_new");
  me->uid = strdup(username); 
  me->pw = strdup(password); 
  me->retry = NO; 
  me->proxy = NO; 
  return me;
}

And in my www_request function,

  // Structure holding authentication info
  MYBasic * basic;

  HTAlert_setInteractive(NO);

  /* Automatic Authentication */
  if (username && password) {
    basic = MYBasic_new(username,password);
    HTBasic_generate (request, basic, 0);
  }

Try setting the proxy flag to YES and see what you get. I don't remember
why I had to set it to NO...
