Contract

  1. RequestVarsReplacer expands http.vars placeholders set via context variables
  2. RequestVarsReplacer evaluates standard HTTP request placeholders including method, host, header, and query parameters
  3. VarsMiddleware sets context variables and expands nested placeholders in variable values
  4. VarsMatcher correctly matches requests based on variable values and placeholder criteria
  5. SetVar with nil value removes the variable from the request context and replacer returns empty string
