@ -78,13 +78,17 @@ The cache can be regenerated at any time by accessing the `/clear_cache` endpoin
If `--cache-file` is set, the cache will be loaded from the specified file on start, and written to the file whenever it is re-generated.
If the `-i|--index` flag is passed, four additional endpoints are registered.
## Info
If the `-i|--info` flag is passed, six additional endpoints are registered.
The first of these—`/html` and `/json`—return the contents of the index, in HTML and JSON formats respectively.
If `--page-length` is also set, these can be viewed in paginated form by appending `/n`, e.g. `/html/5` for the fifth page.
This can prove useful when confirming whether the index is generated successfully, or whether a given file is in the index.
The other two endpoints—`/extensions` and `/mime_types`—return the registered file types.
The remaining four endpoints—`/available_extensions`, `/enabled_extensions`, `/available_mime_types` and `/enabled_mime_types`—return information about the registered file types.
## Statistics
@ -92,6 +96,8 @@ If the `--stats` flag is passed, an additional endpoint, `/stats`, is registered
When accessed, this endpoint returns a JSON document listing every file served, along with the number of times it has been served, its filesize, and timestamps of when it was served.
If `--page-length` is also set, this can be viewed in paginated form by appending `/n`, e.g. `/stats/5` for the fifth page.
## Russian
If the `--russian` flag is passed, everything functions exactly as you would expect.
