AFAIK, the CGI protocol doesn't specify anything regarding custom
headers. It only specifies mandatory variables but leaves custom headers
to the webserver implementation. Apache forwards most headers in
environment variables (http://httpd.apache.org/docs/trunk/env.html).
But, CustCgi only reads a set of known variables listed in CgiVarNames.

Can you try

HTTPDecode(GetEnvironmentVariable('Filename'));

to get your custom header?

A good practice is to start your custom headers with 'X-YourAPP-'.
Headers starting with 'X-' are in a lot of implementations considered as
application specific headers and not touched by transport agents.

If this is indeed the case, then I will add a GetCustomHeader to the TRequest.
TResponse has SetCustomHeader() so this is nicely symmetric.

That would be very handy!

[Lazarus] fcl-web deleted headers?

2014-03-27 Thread Leonardo M . Ramé 
Hi, I'm sending a custom header I called Filename to a Brook CGI
(which uses TRequest from fcl-web) but I can't access that header.

Here's what I capture on the Network tab on Chrome's developer tools;

POST /cgi-bin/gtir2/test/ HTTP/1.1
Host: 127.0.0.1:8080
Connection: keep-alive
Content-Length: 36409
Origin: http://127.0.0.1:8080
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like 
Gecko) Chrome/35.0.1897.2 Safari/537.36
Filename: 1234
Content-Type: application/vnd.oasis.opendocument.text
Accept: */*
Referer: http://127.0.0.1:8080/gtirii/
Accept-Encoding: gzip,deflate,sdch
Accept-Language: es-419,es;q=0.8,en;q=0.6

And here's what I capture with fcl-web:

Accept:*/*
Accept-Encoding:gzip,deflate,sdch
Accept-Language:es-419,es;q=0.8,en;q=0.6
Connection:keep-alive
Content-Length:36409
Content-Type:application/vnd.oasis.opendocument.text
Referer:http://127.0.0.1:8080/gtirii/
Server:127.0.0.1
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like 
Gecko) Chrome/35.0.1897.2 Safari/537.36
Host:/
Cache-Control:/var/www/index.html
X-Requested-With:127.0.0.1

The code I'm using to print the header's output is this (on a POST
handler):

  for I := 0 to TheRequest.FieldCount - 1 do
  begin
lAccession := lAccession + 
  TheRequest.FieldNames[I] + ':' + TheRequest.FieldValues[I] + 'br';
  end; 
  raise Exception.Create(lAccession); 

Why the difference?

Btw, I'm using fpc 2.7.1 compiled from trunk just before asking here, on
linux x86_64 and Lazarus trunk.
