User-Agent

Post by plank » Tue Mar 04, 2003 10:51 pm

After installing Avant Browser, why does my IE broser now incorrectly report it's user-agent as Avant Browser [avantbrowser.com] ?

This goes against what the FAQ says, and makes any avant browser usage figures meaningless.

FAQ:
=================================
Does Avant Browser modify settings of Internet Explorer?

User is able to user Avant Browser to modify the home page of Internet Explorer. But Avant Browser doesn't modify other settings of Internet Explorer.
=================================

I understand it's based on the IE core, but changing headers behind the scenes like this seems unacceptable.

can you give us an example? Is there a website I can check this out for myself? Thanks.

You are correct. Not sure why it does that. But then again, not sure why anyone would mind that much... ???. I suggest e-mailing the author if you really find it offensive.

So is this forum not a place to bring up serious software flaws with the author ?

it is. it's a place to discuss these issues as well for the whole community. The author is better reached, however, at his e-mail address. I suggest sending him an e-mail if you consider this such a serious offense. Here on the forum you'll just get responses from me and smoe other members on what we think, but none of us can do anything about it. The author is the only one who does any of the coding and makes the decisions ;)

Hi Plank,

If you want to remove it then open REGEDIT and traverse to the following hive:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform


and delete the String Value:
Avant Browser [avantbrowser.com]


you will need to repeat this every time you upgrade/reinstall the browser as it is recreated each time :)

-Rich

Thanks auroras - useful information.


In reply to anybody who doesn't get the point, the USER_AGENT field is used by web servers, and web developers to detect what brand and version of web browser is viewing a website.

Obvious uses of this are browser usage statistics, and for generating special content specific to certain brands/versions of browser to make use of whatever features or funkyness exists in all these different versions.

Once this field is screwed up, browser usage statistics become meaningless, and web developers can't guarantee to make content functional in all browsers.

Some people choose to hide the USER_AGENT and other information from web servers for privacy, but to have this changed to an incorrect value without permission or being informed is bad practice.

Plank,

you are completely right in what you are saying but the changing of the User-Agent is not a big problem for AB because in almost ALL cases, when a server gets an User-agent it does not know, it defaults to Internet Explorer pages, so AB can handle them good.

But as I said... AB should not do it to be completely IE compliant!

Regards,

T-PO

Yep, that's what I get in white print on a black screen--strange.  I'm using Win98SE so it's not XP.

I just tried an "experiment"...

I backed up all my ini's, then uninstalled Avant and rebooted.

The User-Agent entry in the registry was still there, even after uninstall.


Also, if you have other browser-shells that place an entry under

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform

(I have two other browser-shells that have the option to add or remove their entries)

, Avant will delete their entries instead of just adding it's "name" to the list.  

Avant deletes them everytime you run it :(.
I'm running:

Win98SE / IE 6 SP1 / Latest Version of Maxthon / Latest Official Version of Avant

Ignore that link from before then - it just came up on google - it does now indeed always return the same text.

I'm certain that I tested it in a couple of browsers before posting - but, instead of accusing that site owner of having a twisted sense of humor, use this instead:

http://zpin.com/user_agent.htm

Anyways, I noticed this through a packet sniif from ethereal - that's the sure way if you really want to see the evidence.
