+ * Main class of the HTTP traffic capture tool.
+ * Captures are triggered by the sun.net.http.captureRules system property.
+ * If set, it should point to a file containing the capture rules.
+ * Format for the file is simple:
+ * - 1 rule per line
+ * - Lines starting with a # are considered comments and ignored
+ * - a rule is a pair of a regular expression and file pattern, separated by a comma
+ * - The regular expression is applied to URLs, if it matches, the traffic for
+ *   that URL will be captured in the associated file.
+ * - if the file name contains a '%d', then that sequence will be replaced by a
+ *   unique random number for each URL. This allow for multi-threaded captures
+ *   of URLs matching the same pattern.
+ * - Rules are checked in sequence, in the same order as in the file, until a
+ *   match is found or the end of the list is reached.
+ *
+ * Examples of rules:
+ * www\.sun\.com , sun%d.log
+ * yahoo\.com\/.*asf , yahoo.log

+/**
+ * This class is used to parse the information in WWW-Authenticate: and Proxy-Authenticate:
+ * headers. It searches among multiple header lines and within each header line
+ * for the best currently supported scheme. It can also return a HeaderParser
+ * containing the challenge data for that particular scheme.
+ *
+ * Some examples:
+ *
+ * WWW-Authenticate: Basic realm="foo" Digest realm="bar" NTLM
+ *  Note the realm parameter must be associated with the particular scheme.
+ *
+ * or
+ *
+ * WWW-Authenticate: Basic realm="foo"
+ * WWW-Authenticate: Digest realm="foo",qop="auth",nonce="thisisanunlikelynonce"
+ * WWW-Authenticate: NTLM
+ *
+ * or
+ *
+ * WWW-Authenticate: Basic realm="foo"
+ * WWW-Authenticate: NTLM ASKAJK9893289889QWQIOIONMNMN
+ *
+ * The last example shows how NTLM breaks the rules of rfc2617 for the structure of
+ * the authentication header. This is the reason why the raw header field is used for ntlm.
+ *
+ * At present, the class chooses schemes in following order :
+ *      1. Negotiate (if supported)
+ *      2. Kerberos (if supported)
+ *      3. Digest
+ *      4. NTLM (if supported)
+ *      5. Basic
+ *
+ * This choice can be modified by setting a system property:
+ *
+ *      -Dhttp.auth.preference="scheme"
+ *
+ * which in this case, specifies that "scheme" should be used as the auth scheme when offered
+ * disregarding the default prioritisation. If scheme is not offered, or explicitly
+ * disabled, by {@code disabledSchemes}, then the default priority is used.
+ *
+ * Attention: when http.auth.preference is set as SPNEGO or Kerberos, it's actually "Negotiate
+ * with SPNEGO" or "Negotiate with Kerberos", which means the user will prefer the Negotiate
+ * scheme with GSS/SPNEGO or GSS/Kerberos mechanism.
+ *
+ * This also means that the real "Kerberos" scheme can never be set as a preference.

+ * This class provides HTTPS client URL support, building on the standard

+ * but differs in the transport layer which it uses:  <UL>
+ *
+ *      <LI>There's a <em>Secure Sockets Layer</em> between TCP
+ *      and the HTTP protocol code.
+ *
+ *      <LI>It uses a different default TCP port.
+ *
+ *      <LI>It doesn't use application level proxies, which can see and
+ *      manipulate HTTP user level data, compromising privacy.  It uses
+ *      low level tunneling instead, which hides HTTP protocol and data
+ *      from all third parties.  (Traffic analysis is still possible).
+ *
+ *      <LI>It does basic server authentication, to protect
+ *      against "URL spoofing" attacks.  This involves deciding
+ *      whether the X.509 certificate chain identifying the server
+ *      is trusted, and verifying that the name of the server is
+ *      found in the certificate.  (The application may enable an
+ *      anonymous SSL cipher suite, and such checks are not done
+ *      for anonymous ciphers.)
+ *
+ *      <LI>It exposes key SSL session attributes, specifically the
+ *      cipher suite in use and the server's X509 certificates, to
+ *      application software which knows about this protocol handler.
+ *
+ *      </UL>
+ *
+ * <P> System properties used include:  <UL>
+ *
+ *      <LI><em>https.proxyHost</em> ... the host supporting SSL
+ *      tunneling using the conventional CONNECT syntax
+ *
+ *      <LI><em>https.proxyPort</em> ... port to use on proxyHost
+ *
+ *      <LI><em>https.cipherSuites</em> ... comma separated list of
+ *      SSL cipher suite names to enable.
+ *
+ *      <LI><em>http.nonProxyHosts</em> ...
