Apache Web Serverg changing caching directory location /tmp to other directory location /appsdata

[Pal RR <palrr57@xxxxxxxxx>]

I am new to apache. I am running apache2 on Ubuntu 14.04 . All files are caching in /tmp directory before sending to application server. /tmp directory does not have enough disk free(empty) space. I have bigger free disk space on /appsdata directory

Please give me example, how I can change apache web server caching directory location /tmp to other directory location /appsdata

Thank you,

Pal RR
