Hints For Debugging Wapp Applications
=====================================

Here are some suggestions for debugging Wapp applications:

  +  If it seems like the [wapp-param](#wapp-param) command is not 
     working correctly, that might be because the same-origin policy
     is preventing query parameters from being parsed.
     Try adding this command to the top of the page generator proc, at
     least temporarily to see if that clears the problem.

  +  If parts of your webpage do not appear to be working, that might
     be due to the restrictive default 
     [Content Security Policy (CSP)](https://en.wikipedia.org/wiki/Content_Security_Policy)
     that Wapp uses.  Try temporarily disabling the CSP using a command
     like <blockquote><b>wapp-content-security-policy off</b></blockquote>
     near the top of your page-generator proc.

  +  Temporarily insert the output of the 
     [wapp-debug-env](commands.md#debug-env) command in your output to see
     what is going on.  Example:
     
> > 
    wapp-trim {
      <h1>Environment</h1>
      <pre>%html([wapp-debug-env])</pre>
    }
