Public predicates
-----------------

.. index:: serve/4
.. _http_static_files/0::serve/4:

``serve/4``
^^^^^^^^^^^

Serves a relative request path from the given document root using the default options and returns a normalized response.

| **Compilation flags:**
|    ``static``

| **Template:**
|    ``serve(Path,Request,DocumentRoot,Response)``
| **Mode and number of proofs:**
|    ``serve(+atom,+compound,+atom,-compound)`` - ``one_or_error``

| **Exceptions:**
|    ``Path`` is not a safe document-root relative path:
|        ``domain_error(http_docroot_relative_path,Path)``
|    ``Request`` is not a valid normalized HTTP request term:
|        ``domain_error(http_request,Request)``
|    ``DocumentRoot`` is not a valid absolute document root path:
|        ``domain_error(http_docroot_document_root,DocumentRoot)``
|    ``DocumentRoot`` is not an existing static-files document root:
|        ``domain_error(http_static_files_document_root,DocumentRoot)``
|    The generated response violates normalized HTTP response semantics:
|        ``domain_error(http_header_semantics,Header)``

.. index:: serve/5
.. _http_static_files/0::serve/5:

``serve/5``
^^^^^^^^^^^

Serves a relative request path from the given document root using the given options and returns a normalized response.

| **Compilation flags:**
|    ``static``

| **Template:**
|    ``serve(Path,Request,DocumentRoot,Options,Response)``
| **Mode and number of proofs:**
|    ``serve(+atom,+compound,+atom,+list(compound),-compound)`` - ``one_or_error``

| **Exceptions:**
|    ``Path`` is not a safe document-root relative path:
|        ``domain_error(http_docroot_relative_path,Path)``
|    ``Request`` is not a valid normalized HTTP request term:
|        ``domain_error(http_request,Request)``
|    ``DocumentRoot`` is not a valid absolute document root path:
|        ``domain_error(http_docroot_document_root,DocumentRoot)``
|    ``DocumentRoot`` is not an existing static-files document root:
|        ``domain_error(http_static_files_document_root,DocumentRoot)``
|    ``Options`` is a variable or a partial list:
|        ``instantiation_error``
|    ``Options`` is neither a variable nor a list:
|        ``type_error(list,Options)``
|    An element ``Option`` of the list ``Options`` is neither a variable nor a compound term:
|        ``type_error(compound,Option)``
|    An element ``Option`` of the list ``Options`` is a compound term but not a valid option:
|        ``domain_error(option,Option)``
|    The generated response violates normalized HTTP response semantics:
|        ``domain_error(http_header_semantics,Header)``
