[users@httpd] Apache Web Serverg changing caching directory location /tmp to other directory location /appsdata

[Pal RR <pa...@gmail.com>]

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
