Thanks for the great article. One thing I didn't understand is: Where does home.html parse {{name}} from?

[Leandro Proença]

Using sed:

  RESPONSE=$(cat home.html | \
    sed "s/{{$COOKIE_NAME}}/$COOKIE_VALUE/")

Did I answer your question?

[David]

Thanks for the reply. Not quite. shouldn't there be a name= somewhere?

Informative post!

I will let you know, you define the function as handleRequest however in one call of it you misname it: cat response | nc -lN 3000 | processRequest

Just want to give big thanks for this awesome post. Seriously great stuff!

The cat trick does not work for me. When I try to understand what is happening in Chrome DevTools it shows me this:

Apparently the server is not able to parse correctly the HTML file. Did you have this problem before?

[Leandro Proença]

never seen this before. maybe OS issue? netcat implementation issue?

anyway, try using \n instead of \r\n

[Vinícius Gajo]

Maybe the problem is the OS or the IDE I'm using (Emacs). I tried setting explicitly the \r\n but it did not work either. But, it worked after I set the headers in the string, and just cat the HTML content, like this:

RESPONSE="HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n$(cat html/home.html)"

[Leandro Proença]

good catch! yes, unfortunately when dealing with stuff low-level we may face OS/tools implementations issues

Hi, can you wrap it all up in a github repo please if you have not done so already ?
