Re: How to retrieve IP address of incoming packets in text file using httpd source code

[Bhavna Saini <bhavnasaini10@xxxxxxxxx>]

Hi Eric,

In the previous mail you mentioned that "webserver can't write to /file.txt from a child process". I couldn't get it properly. Please give some more details of it.

Actually I want to retrieve the IP addresses of incoming requests as soon as it reaches the server and want to save it in a file. Please let me know using which source code file of apache web server I can perform it.

Thanks,

-Bhavna

Your webserver can't write to /file.txt from a child process.
