Can't see the gzip parameter on the response header of my website #6238

Closed fbugissues closed 9 years ago

Originally reported on Google Code with ID 6115

In the latest releases of Firebug I noticed I can't see the gzip parameter on response
headers of my web site http://www.redracingparts.com.
I tested my pages with other tools and all is working good.
So how can I solve that issue?
Does anyone know solution of that problem?

Pls note the issue is the same as in the latest non beta firebug version.

It works fine for me using FF 17.0.1 + FB 1.11 (final) on Win7.

So please update your browser and Firebug and try it again. Does it work for you then?

It also seems to work for me. When I load the page and explore the 
http://www.redracingparts.com/english/motorbikesmotorcycles/introducingpages/11/22/hotproducts.php
request I can see:

Content-Encoding    gzip

in the response headers

Tested with Firebug 1.11

@red, can you please retest?

I've just tested once again by FF 17.0.1, Windows XP and Firebug 1.11.0 and this is
the answer:

Cache-Control   max-age=604800
Connection  Keep-Alive

Content-Type    text/html; charset=iso-8859-1

Let me know.

Thanks

Please follow the steps at https://getfirebug.com/firstaid. So you can find out what's
causing this.
Also you can compare the result in Firebug with the one of the Firefox built-in Web
Console (available via Ctrl+Shift+K).
I assume it may be some setting in your Firefox profile.

I've attached a copy of the screen-shoot with Firefox built-in Web Console and Firebug.

Thanks

From the screenshot I can see that you have several Firebug extensions installed.
Please disable them and try it again. Do you see the Content-Encoding header then?

I attached a screenshot of how it's looking for me.

I've attached the new scree-shoot without extensions.
But I can't see the Content-Encoding header.

Thanks

Isn't that weird that Content-length for Sebastian is: 6939 (for me it's 6914)
and for red it's: 48301 - like the gzip is really not in action...?

I confirm gzip is working on my web site.
This the response header of the same page from http://www.gidnetwork.com/tools/gzip-test.php
using Firefox.

Regarding comment 9:
Of course it's not gzipped for Gio. The question is why. Though it seems to be unrelated
to Firebug.

Regarding comment 8:
Ok, so it doesn't look like it's related to another extension.

Gio, could you please follow the other steps at https://getfirebug.com/firstaid#Isolating_the_problem
as I wrote before and tell us what you see?
Primarily, does the issue go away using a new Firefox profile? Does it make any difference
whether Firebug is installed or not on that new profile?

Hi Sebastian,
the cause is Kaspersky Interner Secutiry 2013.
In fact with Kas IE 2013 off the problem disappears.
So, what should I do now?

Thanks for the info.
I don't have Kaspersky, but a quick google search turned out that already several people
are complaining about that.
There may be an option to control the compression in their web security module.

If you can't find any way to disable that behavior, you should contact Kaspersky. Though
there was already a German doing so some weeks ago and he didn't get any answer yet:

http://gwendragon.de/blog/Computer/Anwendungen/Bugs/kaspersky-antivirus-2012-kein-gzip-bei-html

Anyway, since Firebug isn't involved in that, I close this issue now.

Thanks guys, i just lost 6 hours double checking PHP, PHP extensions, Apache, Apache
extension, Cloudflare, Firefox and on the end firebug and then I bumped on this thread
and realased that it's not my fault, it's KIS 2013.
