Clean cache associated with /vsicurl/ and related file systems

vsi_curl_clear_cache() cleans the local cache associated with /vsicurl/ (and related file systems). This function is a wrapper for VSICurlClearCache() and VSICurlPartialClearCache() in the GDAL Common Portability Library. See Details for the GDAL documentation.

Usage

vsi_curl_clear_cache(partial = FALSE, file_prefix = "")

Arguments

partial: Logical scalar. Whether to clear the cache only for a given filename (see Details).
file_prefix: Character string. Filename prefix to use if partial = TRUE.

Value

No return value, called for side effects.

Details

/vsicurl/ (and related file systems like /vsis3/, /vsigs/, /vsiaz/, /vsioss/, /vsiswift/) cache a number of metadata and data for faster execution in read-only scenarios. But when the content on the server-side may change during the same process, those mechanisms can prevent opening new files, or give an outdated version of them. If partial = TRUE, cleans the local cache associated for a given filename (and its subfiles and subdirectories if it is a directory).
