Hi Andre,
please see below input and output of:
protected String encodeToken(String username, String value)
{
StringBuilder sb = new StringBuilder();
sb.append(username);
sb.append(":");
sb.append(value);
return Base64.encodeBytes(sb.toString().getBytes());
}
Input is:
username= itay.sa...@gmial.com
value= 6de5ca4f:1254c461110:-7feb:9135486247122677484
Output is (this is what actually addCookie get as parameter):
6de5ca4f:1254c461110:-7feb:9135486247122677484
Can you suggest solution ?
