Example

The following obj.conf code instructs sed-request to encode any (<) and (>) characters posted in an HTML form:

Input fn="insert-filter"
      method="POST"
      filter="sed-request"
      sed="s/</&lt;/g"
      sed="s/%3c/&lt;/g"
      sed="s/%3C/&lt;/g"
      sed="s/>/&gt;/g"
      sed="s/%3e/&gt;/g"
      sed="s/%3E/&gt;/g"

Because POST bodies are usually URL-encoded, it is important to check for URL-encoded forms when editing POST bodies. %3C is the URL-encoded form of (<) and %3E is the URI-encoded form of (>).
