Question

I have got a problem.
When I try to do this

connection.setRequestProperty("Sample", "Sample data \n");

I get java.lang.IllegalArgumentException:
Why I need to do this.
Coz my friend gave me challenge to add this to a server. I am confused. Please help me whether it is possible or not to add a escape character to a URLConnection property.

Answer 1

Try encoding the value

connection.setRequestProperty("Sample", URLEncoder.encode("Sample data \n", "UTF-8"));
