Specifying Parameters in a URL

You pass arguments in a URL using query parameters. Those parameters are specified in the form parameterName=value.

A parameter list is appended to a URI after a "?". Multiple parameters are separated by "&", as shown here:

<syntaxhighlight lang="vbnet">

 https://{yourDomain}/networking/{targetAddress}?parameterName1=value1&parameterName2=value2

</syntaxhighlight>

For boolean arguments, the value passed can be "1" or "true", "0" or "false".

Note: When specifying a URL in code, any special characters (characters other than letters and numbers) need to be encoded. For example, a space character can be encoded using either + or %20. (Browsers typically take care of encoding URLs entered into the address bar--so the URL displayed after visiting a page may differ somewhat from the one that was initially entered.) Here are some typical encodings: space + % %20 or + %2B %25 So: Instead of Use & (A&B) space (A B) %26 (A%26B) %20 (A%20B) It can be hard to get be hard to get the encoding right, so it's desirable to use a language library designed for the purpose.
