I have an Apache issue: I can't setup any kind of input filter for mod_ext_filter (ExtFilterDefine).
The same filter defined as output works fine, but defined as input ends into an error. It isn't a matter of SetOutputFilter / SetInputFilter !!!
The error is:
[error] [client 18.104.22.168] (9)Bad file descriptor: apr_file_close(child input)
Actually, whatever the command defined in ExtFilterDefine, it is the same error as upper (cmd="/notanexe" or cmd="/bin/sed s|a|b|g" ), so it sounds more an internal module error when it's an input filter.
Did any of u already try input filter with mod_ext_filter ?
(I always did with output, that's my 1st time trying input).
