                     throws java.io.IOException,
                            java.io.UnsupportedEncodingException

Writes a string into URL-encoded format out to a Writer.

All characters before the start of the query string will be encoded using ISO-8859-1. PENDING: Ideally, we'd encode characters before the query string using UTF-8, which is what the HTML spec recommends. Unfortunately, the Apache server doesn't support this until 2.0.

Characters after the start of the query string will be encoded using a client-defined encoding. You'll need to use the encoding that the server will expect. (HTML forms will generate query strings using the character encoding that the HTML itself was generated in.)

All characters will be encoded as needed for URLs, with the exception of the percent symbol ("%"). Because this is the character itself used for escaping, attempting to escape this character would cause this code to double-escape some strings. It also may be necessary to pre-escape some characters. In particular, a question mark ("?") is considered the start of the query string.

Parameters:

out - a Writer for the output

text - the unencoded (or partially encoded) String

queryEncoding - the character set encoding for after the first question mark

Throws:

java.io.IOException

java.io.UnsupportedEncodingException
