Codam [42 Network] group project: write an HTTP server.
Project description
asynchronous, non-blocking HTTP server in C++ inspired by NGINX.
Project requirements
The configuration file should contain at least one server block that is used to group configuration details for a specific domain. Multiple server blocks can be configured to host multiple domains on a single server. A server block can contain one or more location blocks to route requests for further configuration. Server and location blocks consist of directives and their parameters and end with a semicolon ;. Comments are prefixed by a hash #.
| Server Block Directives | Parameters | Description |
|---|---|---|
listen |
host or host:port or port |
If not specified the default port is 80 and it will accept connections from any IP 0.0.0.0:80 |
server_name |
Either a single server name example.com or multiple server names example example.org example.net |
If multiple server blocks have an exact match on the listen directive, the server looks for an exact match on the server name(s) of these blocks. If no exact match is found, the request will be handled by the first server block |
root |
www/example/ |
Specifies the root directory that will be used to search for a file. Will be the default for any location block within that server block that doesn't specify a root or alias |
error_page |
status_code custom_error_page |
Serve custom pages for certain HTTP response codes |
client_max_body_size |
size_in_megabytes |
Limit the maximum size of a client's request body |
| Location Block Directives | Parameters | Description |
|---|---|---|
allowed_methods |
GET and/or POST and/or DELETE |
The allowed request methods for a specific route |
return |
either 301 302 303 307 308 followed by the redirect_location |
Redirect a client to a new domain name |
root |
www/example/ |
Specifies the root directory that will be used to search for a file for a specific location. It overrides the root specified in the server block |
alias |
/www/test |
Defines a replacement for the specified route. If /example is aliased to /www/test the url /example/one/two/three is /www/test/one/two/three. alias overrides both the root directive in the server and location block. |
autoindex |
Either on or off |
Turn on or off directory listing (off by default) |
default_file |
Either a single file index.html or multiple files index.html index.htm |
The server searches for the files in the specified order and returns the first one it finds. If default_file is not specified, index.html is set as the default file |
cgi |
file_extention path_to_executable |
Executes cgi based an a certain file extension. Currently the execution of .py scripts are implemented |
file_upload |
path_to_upload_location |
If not specified, files will be uploaded to the root directory |
