400 error on long URLs

[p-mitana]

I need to support long GET queries in my application (I'm implementing a service that generates images based on the GET parameters to be embedded in Markdown file). However, above 4096 (I expect, as ~3600 character long URL worked properly) characters in URL I get 400 error:

400 - Bad Request

Bad Request

Internal error information:

@the-Mitu increase maxRequestHeaderSize in httpSettings

https://github.com/vibe-d/vibe.d/blob/82222e425bff5af2b5a683b6f5bbc75a3e90a2cb/http/vibe/http/server.d#L663

Hi, I'm getting this error as well however I have set maxRequestHeaderSize to 10MB and still getting this issue. Could this have something to do with MaxHTTPHeaderLineLength?
