Sergey,
The issue with IE11 (maybe other earlier versions of IE too) is that IE
builds the Authentication header differently. Chrome/FF put a space in
between each name/value pair and IE doesn't. I tweaked the parse_headerfunction
to account for this and IE 11 now works.
IE header sample:
"Digest
username=\"admin\",realm=\"xetawave\",nonce=\"1390849663\",uri=\"/protected/cgi-bin/helloDate.cgi\",cnonce=\"e02ae08fdffcc05ba8169b3d9feee890\",nc=00000001,response=\"bc3fbe334b57b9b77a74bdee7fc490f6\",qop"...
Chrome header sample:
"Digest username=\"admin\", realm=\"xetawave\", nonce=\"1390835128\",
uri=\"/protected/cgi-bin/helloDate.cgi\",
response=\"c6ade1754b8868b646a6d51ec82eebe4\", qop=auth, nc=00000015,
cnonce=\"5faf32dd1f395363\""
Modified parse_header function (my changes highlighted in yellow, it
assumes that a comma will never be a character in a value, so this might be
a problem):
int parse_header(const char *str, int str_len, const char *var_name, char
*buf,
size_t buf_size) {
int ch = ' ', len = 0, n = strlen(var_name);
const char *p, *end = str + str_len, *s = NULL;
if (buf != NULL && buf_size > 0) buf[0] = '\0';
// Find where variable starts
for (s = str; s != NULL && s + n < end; s++) {
if ((s == str || s[-1] == ' ' || s[-1] == ',') && s[n] == '=' &&
!memcmp(s, var_name, n)) break;
}
if (s != NULL && &s[n + 1] < end) {
s += n + 1;
if (*s == '"' || *s == '\'') ch = *s++;
p = s;
while (p < end && p[0] != ch && p[0] != ',' && len < (int) buf_size) {
if (p[0] == '\\' && p[1] == ch) p++;
buf[len++] = *p++;
}
if (len >= (int) buf_size || (ch != ' ' && *p != ch)) {
len = 0;
} else {
if (len > 0 && s[len - 1] == ',') len--;
if (len > 0 && s[len - 1] == ';') len--;
buf[len] = '\0';
}
}
return len;
}
Thanks,
Ben
