Dynamically Rewriting References
URL references can be either relative or absolute. Relative references specify the location of the
resource relative to the base document. For example, consider the directory structure shown in
“Relative and Absolute References” (page 178).

Graphics
www.acme.com
index.html
picture.gif
other_Docs
HTML_Docs
Relative Reference = “graphics/picture.gif”
Absolute Reference = “/HTML_Docs/Graphics/picture.gif”
Depending on how you configure the content server, the content server either leaves all references
as they are or converts them in one of these ways:
• Converts all absolute references to relative reference
• Converts some absolute references to relative references
• Converts some relative references to absolute references
Whether references are absolute or relative can affect the lifetime of tickets.
HTML and Image References
References fall into two categories: HTML and image.
HTML references include:
• <a href ="xxxx">
• <form action ="xxxx">
• <area href="xxxx">
