Subject Re: [users@httpd] Filtering incoming request with mod_ext_filter
Date Wed, 23 Oct 2013 19:18:58 GMT
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? 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
