Examples with CharArrayBuffer org.apache.http.util.CharArrayBuffer used on opensource projects

Example 1 with CharArrayBuffer

use of org.apache.http.util.CharArrayBuffer in project android_frameworks_base by ParanoidAndroid.

the class HttpHeaderTest method testCacheControl.

/**
     * Tests that cache control header supports multiple instances of the header,
     * according to HTTP specification.
     *
     * The HTTP specification states the following about the fields:
     * Multiple message-header fields with the same field-name MAY be present
     * in a message if and only if the entire field-value for that header field
     * is defined as a comma-separated list [i.e., #(values)]. It MUST be
     * possible to combine the multiple header fields into one "field-name:
     * field-value" pair, without changing the semantics of the message, by
     * appending each subsequent field-value to the first, each separated by a
     * comma. The order in which header fields with the same field-name are
     * received is therefore significant to the interpretation of the combined
     * field value, and thus a proxy MUST NOT change the order of these field
     * values when a message is forwarded.
