Create options for static paths
staticPathOptions(
indexhtml = TRUE,
fallthrough = FALSE,
html_charset = "utf-8",
headers = list(),
validation = character(0),
exclude = FALSE
)If an index.html file is present, should it be served up when the client requests the static path or any subdirectory?
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.
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.
Additional headers and values that will be included in the response.
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.
Should this path be excluded from static serving? (This is
only to be used internally, for excludeStaticPath.)
