I'll make a small FPC sample with GET in SCGI and send it here ...
Great, please do.
Done! =)
Tested with FCL and Synapse (demo in attached or in Dropbox:
https://www.dropbox.com/s/rei2fj5papyqium/SCGI_GET.zip?dl=0). My demo is
just a "hello world", showing how to do a GET in a SCGI application. I'm using
only sockets, but it can be easily implemented with
HTTPDefs.pas pre-implementation, to make something like custscgi.pas.
Below you can see how to test my small app in seven steps, on Windows 7 and
using nginx as HTTP server. It is very easy to do, please
see:
1. download the nginx server http://nginx.org/en/download.html (I'm using the
nginx-1.7.9);
2. unpack nginx-1.7.9.zip, and in nginx-1.7.9 folder, open the
nginx-1.7.9\conf\nginx.conf file;
3. in nginx.conf file, add the following content (see my nginx.conf here:
http://pastebin.com/7xB6nmJz, line 79):
location /test {
include scgi_params;
scgi_pass localhost:8080;
}
4. open the CMD, go into the nginx-1.7.9 folder using CD, and execute nginx.exe;
5. compile and run the SCGI_GET\FCL\project1.lpr project;
6. open the http://localhost/test URL in you browser;
7. enjoy! =)
Please tell me if those steps also worked for you.
You can test it in Apache too (Windows or Linux), I tested it using the steps
that I told before and it worked like a charm too.
Now I need to test the SCGI performance comparing it with FastCGI (+- 6.000
request / sec) and Apache module (+- 14.000 requests /
sec).
I'm very impressed with the ease in debugging a SCGI application.
The same can be done with FastCGI if you use mod_fastcgi and
ExternalFastCGIServer. We do that at work.
Currently, I don't really see the added value in SCGI.
The strange thing of scgi is that the spec is so vague, I am surprised
there are any implementations...
Michael.
Me too. But you can use the same CGI spec to get env. variables, query_string
etc. SCGI is very easy to be implemented like CGI. I've
tested this draft to get all fields of a HTML form with POST:
https://gist.github.com/ArtemGr/38425. I can adapt it to Pascal too.
Please do, because the current implementation is not really useful.
Accepting a socket connection and writing some data is simply "TCP/IP for beginners" :)
Not to mention that it will block if the server sends more than 4k data.
The real work is accepting content and parsing the headers. :)
Michael.
