That's a good question. I don't set it at all. Thanks for pointing that out Jeff.

Now, I face another problem. I want to modify header parameters of incoming request from the Perl script. Is this possible at all?

Maybe if your Perl script runs via mod_perl ;)

mod_ext_filter only provides access to the request and response *bodies*.

I can see headers in the output file but the input file contains just the request body but no header.

Configuration:

ExtFilterDefine myFilterIn ftype=20 mode=input \
cmd="c:/tools/perl/bin/perl.exe c:/temp/dump.pl c:/temp/dump.in"

ExtFilterDefine myFilterOut ftype=30 mode=output \
cmd="c:/tools/perl/bin/perl.exe c:/temp/dump.pl c:/temp/dump.out"

<Directory "c:/Apache24/htdocs">
SetInputFilter myFilterIn
SetOutputFilter myFilterOut

</Directory>

Request:

curl -X POST -H "Content-Type: application/json" -H "custom: 1234567890" -d '{"username":"xyz","password":"xyz"}' http://localhost/api/login

Thanks

Daniel

I try to filter incoming HTTP request. Here is configuration of my filter:

LoadModule ext_filter_module modules/mod_ext_filter.so
ExtFilterDefine myFilter ftype=30 mode=input \
cmd="c:/tools/perl/bin/perl.exe c:/temp/dump.pl c:/temp/dump.out"

<Directory "c:/Apache24/htdocs">
SetOutputFilter myFilter
</Directory>

and Perl script I'm using:

use strict;
open(SAVE, ">$ARGV[0]")

or die "can't open $ARGV[0]: $?";
while (<STDIN>) {
print SAVE $_;

print $_;
}
close(SAVE);

Apache version = httpd-2.4.6-win32-VC11

This doesn't work at all giving me an error "AH00082: an unknown filter was not added: myFilter". However, when I set 'mode' to 'output' it work as expected. Any clue on this?

Were you using "SetInputFilter myFilter" when you had "mode=input"?

Thanks
