For example: --req-header-to-print=User-Agent
|
|
Note that this option is case-insensitive
|
|

## Changelog
|
|
|
|
See the [Changelog.](https://git.seodisparate.com/stephenseo/c_simple_http/src/branch/main/Changelog.md)
|
|
|
|
## Before Compiling
|
|
|
|
Make sure that the git submodule(s) are loaded:
|
|
|
|
git submodule update --init --recursive --depth=1 --no-single-branch
|
|
|
|
Without this, the project will fail to build.
|
|
|
|
## Example
|
|
|
|
# Build the project.
|
|
make c_simple_http
|
|
|
|
# Alternatively, build with cmake.
|
|
cmake -S . -B buildDebug && make -C buildDebug
|
|
|
|
# Run it with the example config.
|
|
# Note that the example config was designed such that it must be referred
|
|
# to from its parent directory.
|
|
./c_simple_http --config=example_config/example.config --enable-static-dir=example_static_dir
|
|
# If built with cmake:
|
|
./buildDebug/c_simple_http --config=example_config/example.config --enable-static-dir=example_static_dir
|
|
|
|
# If port is not specified, the server picks a random port.
|
|
# This program should print which TCP port it is listening on.
|
|
# Sometimes the program will fail to rebind to the same port due to how TCP
|
|
# works. Either wait some time or choose a different port.
|
|
|
|
# Access the website.
|
|
# This assumes the server is hosted on port 3000.
|
|
curl localhost:3000
|
|
|
|
## Other Notes
|
|
|
|
The config file can be reloaded if the program receives the SIGUSR1 signal.
|
|
The `--enable-reload-config-on-change` option automatically reloads the config
|
|
file if the config file has changed.
|
|
|
|
The `--enable-cache-dir=<DIR>` option enables caching and sets the "cache-dir"
|
|
at the same time. `--cache-entry-lifetime-seconds=<SECONDS>` determines when a
|
|
cache entry expires.
|
|
[The default expiry time of a cache entry is 1 week.](https://git.seodisparate.com/stephenseo/c_simple_http/src/commit/3f1be0cf496eab7242ab997262d85af11337039b/src/constants.h#L28)
