Hosts file on S60 3.x Devices
Article Metadata
This article is intended for network application developers, who wish to 'hard-code' IP addresses for certain server names. This mechanism comes in handy when the developer wants to redirect network traffic from a live site to another test site, without the knowledge of the end user.

Concept
The "HOSTS" file is a lookup table. When the network application (such as web browser) requests to create a connection with a network server, the IP address is needed to create the connection. If the requesting application asks for "www.forum.nokia.com", this name must be converted to an IP address. The domain name system consults the HOSTS file to see if there is an entry for "www.forum.nokia.com" in it. If there is, then the IP address given in that entry will be used to create connection to.
This substitution will continue so long as the HOSTS file is present. To revert back to original behavior, one should simply delete this file.
Example HOSTS file:
# This is a sample HOSTS file (taken from a MS-Windows system)
102.54.94.97 rhino.acme.com # source server
38.25.63.10 x.acme.com # x client host
Like all the other advanced operating systems, Symbian includes support for HOSTS file. In all the operating systems, there is always a special place for HOSTS file. E.g. in UNIX like systems, the file goes in /etc . We will now see where to save the HOSTS file on S60 devices.
Pre-PlatSec World
In S60 phones without platform security, this file is located inC:\system\data\hosts
PlatSec World (S60 3.x onwards)
In the recent phones with platform security, this file is located inC:\private\10000882\hosts
Since this is a "private" location, one requires a file browser (or an application) with AllFiles capability to copy the file to this location.


Well, thank you for that information.
But sitting with a S60 3.x based Nokia E90 with a need to modify/create this Hosts-file and no Filemanagers on the market supporting the AllFiles capability, what should one do then ?
Anyone out there having a Hosts-file editor working on 3rd ed. ? Or another clewer trick ?
