apreq_body and apreq_param

[Brian McQueen <mc...@gmail.com>]

I wonder about the differences between apreq_param and apreq_body.  I
see that apreq_param gets a particular param and returns a param
structure, which is a bit of an  odd structure, but its a general way
of representing the data.  When using apreq_body a more intuitive,
string based key/value style is provided through the returned table.
The table interface is easy to use and makes sense, but I am a bit
confused about the emphasis on key/value techniques with apreq_body,
versus some other technique when data is retrieved via apreq_param.
What is the intention behind these two different designs?

Notice the difference of WHAT they parse.

APREQ_DECLARE(apreq_param_t *)apreq_param(apreq_handle_t *req, const char *key);
/**
 * Find the first query string parameter or body parameter with the
 * specified name.  The match is case-insensitive.
 * returns The first matching parameter (with args searched first) or NULL.
 */

apr_status_t apreq_body(apreq_handle_t *req, const apr_table_t **t)

/**
 * Expose the parsed "request body" associated to this handle.
 * The resulting table(t), which will either be NULL or a
 * valid table object on return.
