Well, it's possible, and I will check it. But this is an intranet server, and if I run it as Apache 1.3 everything works. I am also using an external filter with ext_filter_module, maybe ..reading.. means, that the server is waiting for data from that filter... Is there no one of the apache team who can answer me the question, what ..reading.. exactly means? Do I have to check my mod_perl code or does it happen before any perl code is executed?? Thanks for your support, Olivier.
