dump Action

The dump action terminates the request processing and dumps out (intermediate) data to the client.

Syntax

  • in="..." defines the input location (optional, default is fit://request/content)
  • minify="true|false" controls JS/CSS minification (optional, default is true)
  • mime="..." sets the HTTP header field Content-Type to the given value (optional, no default)
  • status="..." sets the HTTP status code to the given value (optional). If no status attribute is set, the HTTP status will remain unchanged. If status has an empty value (e.g. status=""), the HTTP status code is set to 500.

Usage

Before sending out the data specified in in, the dump action makes the following modifications:

  • The meta data of in is used to determine the Content-Type header
  • New cookies received from upstream servers are sent

The following modifications are applied to the content:

  • remaining fit: URIs are stripped or translated
  • JavaScript and CSS content is minified, if not disabled

Examples

<dump />
<dump in="fit://site/public/error.html"/>
<dump in="fit://request/content" status="201" mime="text/plain"/>

The action is handy in debugging situations to terminate the flow at a certain position. In this example we dump the main content after applying regular expressions but before parsing the content:

<flow>
  <request>…</request>
  <regex ... />
  <!-- debug: terminate after regex has been applied -->
  <dump/>

  …
</flow>
