Thank you so much, both of you who answered me,I was wrong when not mentioned about the header. the header, it is "User-Agent" passed to apache server(version 2.2.15)in apache configuration, i used: LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" " combined The option "%{User-Agent}i" is to display header, it works fine for computer, laptop, and apple(iphone, ipad) devicehowever when I use Android then access_log in service side prints out: 172.16.33.124 - - [07/Dec/2012:13:29:37 +0900] "GET /data/playgirls-14.ts HTTP/1.1" 200 2103156 "-" "stagefright/1.2 (Linux;Android 4.0.4)" - client side, the header is: Mozilla/5.0 (Linux; U; Android 4.0.4; ko-kr; SHW-M380W Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Safari/534.30 -> both of them printed "Linux; U; Android 4.0.4", but access_log in server side not print Device ID: SHW-M380W apache access_log hadn't display full header. I had tried to set header "HTTP_USER_AGENT" but it didn't work. Thank you,Chau Pham.

In this case, it would be in the HTTP_USER_AGENT header, which, when I access my server from my Android device, looks like Mozilla/5.0 (Linux; Android 4.2.1; Nexus 7 ... and so on So, yeah, you'd want to log the HTTP_USER_AGENT header. See http://httpd.apache.org/docs/2.4/mod/mod_log_config.html#formats for details on how to configure your log file to log this value. -- Rich Bowen rbo...@rcbowen.com :: @rbowen rbo...@apache.org
