Bug ID: 58842
Summary: mod_proxy DNS cache with authoritative and
no-authoritative DNS Server
Product: Apache httpd-2
Version: 2.4.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy
Assignee: [email protected]
Reporter: [email protected]
Hello everybody,
I am using Apache as a reverse proxy to access an application on a server.
I have two environments :
- In the first environment we have a non-authoritative DNS server
- In the second environment we have an authoritative DNS server.
When I access to the application in the first environment, the
non-authoritative DNS server answers with the value in its cache.
When the non-authoritative DNS server updates the value in its cache, Apache
(mod_proxy) automatically updates the DNS value in its cache.
When I access to the application in the second environment, the authoritative
DNS server answers with the value in its base.
When the authority DNS server updates the value in its base, Apache (mod_proxy)
doesn't update the DNS value in its cache. It only updates when I restart
Apache service.
SO I am tempted to think that :
- If the DNS server is authoritative, Apache saves in its cache the answers
from this DNS server
- If the DNS server is non-authoritative, Apache doesn't save in its cache the
answers from this DNS server
What do you think about it?
Is it right?
Any help would be greatly welcome.
Regards
Broisy
