I do not know if this is the correct forum but... I am passing a URL to the server and receiving a en error:

URL

http://10.15.227.141:8080/searchapi?command=search&layout=searchapi&param1_callid=00002001171433344652&operator_callid=1

ERROR
<errors errorcode="1" errorstring="no layout"/>.

What am I missing here? Also, what is the safest way to pass authentication credentials? (an example would help)
