Additionally the same issue was with memory, but fix is almost ready

Server kills connection even when data is written in it. So this leads to error:

ERROR|Mon, 14  Jun 2021 13:28:18 GMT:Failed to send packet: {error,{closed,<<...>>}} @ io_proxy:tcp_send/2

Rules handler receives host header with space before it. Instead leading space should be removed.
Example:
Request contains Host: example.org, so rules handler get " example.org" instead of "example.org"

Describe the bug
When Default rule is used the headers are cleaned, and only Connection is sent. Thise leads to lack of Content-length header and so browser failing to finalize request correctly.

To Reproduce
In config apply Default rule to some route. Request this route through any client.

Expected behavior
The header MUST NOT be cleaned when using Default rule

OS & client (please complete the following information):

• OS: Any
• Client: Any
• Client options(if applicable): N/A
• Version: Any

As mentioned in issue #7 in order to overcome difficulties with parsing extra space quotes should be introduced.

Server tries to handle get parameters as a file name, i.e. for /foo/bar?a=b it tries to find a file bar?a=b. Server should split get params and attach them to request record instead of attaching it to filename.

Exception:

Error in process <0.495.0> on node 'MeowMeow@e28340418539' with exit value:

  {handle,handler,3,[{file,"/buildroot/src/handle.erl"},{line,251}]}]}

The following should be investigated:

• Whether this is allowed in HTTP/1.0
  • If so whether do we need to support it
• Definitely handle it by returning 400 Bad request

In order to make webserver more flexible the ability for loading rule handlers from separate modules should be implemented.

Describe the bug
When client does HTTP/1.0 request to server with Hosts handling configured the exception on server occurs.

To Reproduce
Any HTTP/1.0 request without Hosts header to MeowMeow server where Hosts handling is configured.

Expected behavior
No exception should occur.

OS & client (please complete the following information):

Testing GET /catnip with Route /catnip in routes.conf results into rules not being added to list of processing

The webserver produces a lot of debug messages which make request handling slower. As the code grows the amount of messages which are sent to logs also grows. So it might be beneficial in future to separate logging in another process in order to deliver response as fast as possible.

Send-File when responding to request behaves as if connection iskeep-alive ignoring that it may be close connection.

The script for testing a web server with help of GitHub CI should be developed.

In Send-File directive wrong path to file(i.e. non-existent or irregular) causes handler process to die with exception. The proper handling of such a misconfiguration should include:

• Displaying an error in log
• Sending error 500 Internal Server Error to client

When the some folder is requested, the server tries to find and send index.html, but if there is no index.html server attempts to read file with name of folder which leads to error.
So if there is no index.html in folder server should send HTTP/1.1 404 Not Found
