#### Building a Table of All Request Headers #### Building a Table of All Request Headers
The following [EWF service](/doc/workbook/headers/header_fields/application.e) code simply uses an ```html_template``` to fill a table (names and values) with all the headers fields it receives. The following [EWF service](/doc/workbook/handling_request/headers/header_fields/application.e) code simply uses an ```html_template``` to fill a table (names and values) with all the headers fields it receives.
The service accomplishes this task by calling ```req.meta_variables``` feature to get an ```ITERABLE [WSF_STRING]```, an structure that can be iterated over using ```across...loop...end```, then it checks if the name has the prefix ```HTTP_``` and if it is true, put the header name and value in a row.
