Topic: mod-security, How to interrupt client request ?

[serg]

I need to interrupt client request on phase 1, to be exact, when HTTP-header Content-length is greater than 100 Mb.

I found two methods how to do this:
1.
SecRule REQUEST_HEADERS:Content-Length "@ge 104857600" "phase:1,deny,redirect:http://server.com"

but this rule works only when whole body of request will be received by the server, it means that client has to wait for several seconds before he will see "http://server.com" page.

2.
SecRequestBodyLimit 104857600
ErrorDocument 413 http://server.com

but, unfortunately, if body is greater than 100 Mb, 413 status error isn't sent as it say in documentation but just connection breaks

Can anyone help me in this problem ?

I use Apache 2.0.59
