Create options for static paths

Create options for static paths

Usage

staticPathOptions(
  indexhtml = TRUE,
  fallthrough = FALSE,
  html_charset = "utf-8",
  headers = list(),
  validation = character(0),
  exclude = FALSE
)

Arguments

indexhtml

If an index.html file is present, should it be served up when the client requests the static path or any subdirectory?

fallthrough

With the default value, FALSE, if a request is made for a file that doesn't exist, then httpuv will immediately send a 404 response from the background I/O thread, without needing to call back into the main R thread. This offers the best performance. If the value is TRUE, then instead of sending a 404 response, httpuv will call the application's call function, and allow it to handle the request.

html_charset

When HTML files are served, the value that will be provided for charset in the Content-Type header. For example, with the default value, "utf-8", the header is Content-Type: text/html; charset=utf-8. If "" is used, then no charset will be added in the Content-Type header.

headers

Additional headers and values that will be included in the response.

validation

An optional validation pattern. Presently, the only type of validation supported is an exact string match of a header. For example, if validation is '"abc" = "xyz"', then HTTP requests must have a header named abc (case-insensitive) with the value xyz (case-sensitive). If a request does not have a matching header, than httpuv will give a 403 Forbidden response. If the character(0) (the default), then no validation check will be performed.

exclude

Should this path be excluded from static serving? (This is only to be used internally, for excludeStaticPath().)
