Adjust the REQUEST_URI query parameter such that it includes the QUERY_STRING if any. In other words, REQUEST_URI should be the second field of the first line of the original HTTP request. This is how Apache and Nginx both work. (check-in: 3028f8c9ea user: drh tags: trunk)

     Change the value of parameter _NAME_ to _VALUE_.  If _NAME_ does not
     currently exist, it is created.

  +  **wapp-param-exists** _NAME_  
     Return true if and only if a parameter called _NAME_ exists for the
     current request.

  +  **wapp-param-list** _NAME_  
     Return a TCL list containing the names of all parameters for the current


     request.  Note that there are several parameters that Wapp uses
     internally.  Those internal-use parameters all have names that begin
     with ".".

  +  <a name='allow-xorigin'></a>**wapp-allow-xorigin-params**  
     Query parameters and POST parameters are usually only parsed and added
     to the set of parameters available to "wapp-param" for same-origin
     requests.  This restriction helps prevent cross-site request forgery
     (CSRF) attacks.  Query-only web pages for which it is safe to accept
     cross-site query parameters can invoke this routine to cause query

     Return true if and only if a parameter called _NAME_ exists for the

  +  **wapp-param-list** _GLOB_  
     Return a TCL list containing the names of all parameters for the current
     request.  The _GLOB_ argument is optional.  If provided, only parameters
     that match the GLOB pattern are returned.  If omitted, `*` is used as the
     GLOB pattern.  Note that there are several parameters that Wapp uses
     internally.  Those internal-use parameters all have names that begin
