### Posting form parameters ([.kt][PostFormKotlin], [.java][PostFormJava])

Use `FormBody.Builder` to build a request body that works like an HTML `<form>` tag. Names and values will be encoded using an HTML-compatible form URL encoding.

      private val client = OkHttpClient()

    /**
     * Displays the not found error page.

     * @return HTML response for the not found error page

    public HtmlResponse index(final ErrorForm form) {
        return asHtml(virtualHost(path_Error_NotFoundJsp));

This platform is agnostic to what exactly the purpose of the work is.
It might be creating an application, setting up development environments, orchestrating deployments, running simulations, etc.

This platform does not provide special support for a particular kind of automation. This is the responsibility of other platforms. 

It is made up of 3 architecture modules:

                            <div class="form-group row">
                                <label for="badWordFile" class="col-sm-3 text-sm-right col-form-label"><la:message
                                    key="labels.bad_word_file"/></label>
                                <div class="col-sm-9">
                                    <input type="file" id="badWordFile" name="badWordFile" class="form-control-file"/>
