+
+Description
+===========
+
+The Traffic Server remap interface provides a simplified mechanism for
+plugins to manipulate HTTP transactions. A remap plugin is not global; it
+is configured on a per-remap rule basis, which enables you to customize
+how URLs are redirected based on individual rules in the remap.config
+file. Writing a remap plugin consists of implementing one or more of the
+remap entry points and configuring the remap.config configuration file to
+route the transaction through your plugin. Multiple remap plugins can be
+specified for a single remap rule, resulting in a remap plugin chain
+where each pligin is given an opportunity to examine the HTTP transaction.
+
+:func:`TSRemapInit` is a required entry point. This function will be called
+once when Traffic Server loads the plugin. If the optional :func:`TSRemapDone`
+entry point is available, Traffic Server will call then when unloading
+the remap plugin.
+
+A remap plugin may be invoked for different remap rules. Traffic Server
+will call the entry point each time a plugin is specified in a remap
+rule. When a remap plugin instance is no longer required, Traffic Server
+will call :func:`TSRemapDeleteInstance`.
+
+:func:`TSRemapDoRemap` is called for each HTTP transaction. This is a mandatory
+entry point. In this function, the remap plugin may examine and modify
+the HTTP transaction.
+
+Return values
+=============
+
+:func:`TSRemapInit` and :func:`TSRemapNewInstance` should return
+:data:`TS_SUCCESS` on success, and :data:`TS_ERROR` otherwise. A
+return value of :data:`TS_ERROR` is unrecoverable.
+
+:func:`TSRemapDoRemap` returns a status code that indicates whether
+the HTTP transaction has been modified and whether Traffic Server
+should continue to evaluate the chain of remap plugins. If the
+transaction was modified, the plugin should return
+:data:`TSREMAP_DID_REMAP` or :data:`TSREMAP_DID_REMAP_STOP`; otherwise
+it should return :data:`TSREMAP_NO_REMAP` or :data:`TSREMAP_NO_REMAP_STOP`.
+If Traffic Server should not send the transaction to subsequent
+plugins in the remap chain, return :data:`TSREMAP_NO_REMAP_STOP`
+or :data:`TSREMAP_DID_REMAP_STOP`.  Returning :data:`TSREMAP_ERROR`
+causes Traffic Server to stop evaluating the remap chain and respond
+with an error.
