## rclone serve http
Serve the remote over HTTP.
### Synopsis
rclone serve http implements a basic web server to serve the remote
over HTTP. This can be viewed in a web browser or you can make a
remote of type http read from it.
Use --addr to specify which IP address and port the server should
listen on, eg --addr 1.2.3.4:8000 or --addr :8080 to listen to all
IPs. By default it only listens on localhost.
You can use the filter flags (eg --include, --exclude) to control what
is served.
The server will log errors. Use -v to see access logs.
--bwlimit will be respected for file transfers. Use --stats to
control the stats printing.
### Directory Cache ###
Using the `--dir-cache-time` flag, you can set how long a
directory should be considered up to date and not refreshed from the
backend. Changes made locally in the mount may appear immediately or
invalidate the cache. However, changes done on the remote will only
be picked up once the cache expires.
Alternatively, you can send a `SIGHUP` signal to rclone for
it to flush all directory caches, regardless of how old they are.
Assuming only one rclone instance is running, you can reset the cache
like this:
kill -SIGHUP $(pidof rclone)
### File Caching ###
**NB** File caching is **EXPERIMENTAL** - use with care!
These flags control the VFS file caching options. The VFS layer is
used by rclone mount to make a cloud storage systm work more like a
normal file system.
You'll need to enable VFS caching if you want, for example, to read
and write simultaneously to a file. See below for more details.
Note that the VFS cache works in addition to the cache backend and you
may find that you need one or the other or both.
--vfs-cache-dir string Directory rclone will use for caching.
--vfs-cache-max-age duration Max age of objects in the cache. (default 1h0m0s)
--vfs-cache-mode string Cache mode off|minimal|writes|full (default "off")
--vfs-cache-poll-interval duration Interval to poll the cache for stale objects. (default 1m0s)
If run with `-vv` rclone will print the location of the file cache. The
files are stored in the user cache file area which is OS dependent but
can be controlled with `--cache-dir` or setting the appropriate
environment variable.
The cache has 4 different modes selected by `--vfs-cache-mode`.
The higher the cache mode the more compatible rclone becomes at the
cost of using disk space.
Note that files are written back to the remote only when they are
closed so if rclone is quit or dies with open files then these won't
get written back to the remote. However they will still be in the on
disk cache.
#### --vfs-cache-mode off ####
In this mode the cache will read directly from the remote and write
directly to the remote without caching anything on disk.
This will mean some operations are not possible
* Files can't be opened for both read AND write
* Files opened for write can't be seeked
* Existing files opened for write must have O_TRUNC set
* Files open for read with O_TRUNC will be opened write only
* Files open for write only will behave as if O_TRUNC was supplied
* Open modes O_APPEND, O_TRUNC are ignored
* If an upload fails it can't be retried
#### --vfs-cache-mode minimal ####
This is very similar to "off" except that files opened for read AND
write will be buffered to disks. This means that files opened for
write will be a lot more compatible, but uses the minimal disk space.
These operations are not possible
* Files opened for write only can't be seeked
* Existing files opened for write must have O_TRUNC set
* Files opened for write only will ignore O_APPEND, O_TRUNC
* If an upload fails it can't be retried
#### --vfs-cache-mode writes ####
In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.
This mode should support all normal file system operations.
If an upload fails it will be retried up to --low-level-retries times.
#### --vfs-cache-mode full ####
In this mode all reads and writes are buffered to and from disk. When
a file is opened for read it will be downloaded in its entirety first.
This may be appropriate for your needs, or you may prefer to look at
the cache backend which does a much more sophisticated job of caching,
including caching directory heirachies and chunks of files.q
In this mode, unlike the others, when a file is written to the disk,
it will be kept on the disk after it is written to the remote. It
will be purged on a schedule according to `--vfs-cache-max-age`.
This mode should support all normal file system operations.
If an upload or download fails it will be retried up to
--low-level-retries times.
