This type of syntax specifies that the response content is fetched from the named file within the static directory. Subdirectories such as filename="sub-dir/file.pdf" are supported.
Variables are not allowed in the filename attribute. This is to prevent accidentally making more files accessible (if the client guesses the right filename) than intended. But you can use Conditional Success Action to deliver different files depending on different parameter values.
<endpoint name="foo">
<success>
<response-from-static filename="path-to-file"/>
</success>
</endpoint>You can optionally add an attribute "download-filename".
If the download-filename="foo.pdf" attribute is present, then the header in the HTTP response is set indicating that the file should be downloaded as opposed to displayed in the browser window. Parameter Values like ${foo} are replaced.
<endpoint name="foo">
<success>
<response-from-static filename="path-to-file" download-filename="my-document.pdf"/>
</success>
</endpoint>Potential Source of Error
Make sure that the filename does not contain empty characters, because this will raise an error.
