# Server
The server section configures and tunes the http server module Authelia uses.
## Configuration
```yaml
# Configuration options specific to the internal http server
server:
# Buffers usually should be configured to be the same value.
# Explanation at https://docs.authelia.com/configuration/server.html
# Read buffer size configures the http server's maximum incoming request size in bytes.
read_buffer_size: 4096
# Write buffer size configures the http server's maximum outgoing response size in bytes.
write_buffer_size: 4096
# Set the single level path Authelia listens on, must be alphanumeric chars and should not contain any slashes.
path: ""
```
### Buffer Sizes
The read and write buffer sizes generally should be the same. This is because when Authelia verifies
if the user is authorized to visit a URL, it also sends back nearly the same size response
(write_buffer_size) as the request (read_buffer_size).
### Path
Authelia by default is served from the root `/` location, either via its own domain or subdomain.
Example: https://auth.example.com/, https://example.com/
```yaml
server:
path: ""
```
Modifying this setting will allow you to serve Authelia out from a specified base path. Please note
that currently only a single level path is supported meaning slashes are not allowed, and only
alphanumeric characters are supported.
Example: https://auth.example.com/authelia/, https://example.com/authelia/
```yaml
server:
path: authelia
```
