favicon.ico

It shows garbage text.

do you use http analyzer tool (e.g. httpfox, fiddler)? you have seen IE sending request to /favicon.icon, haven't you?

HttpFox

Fiddler

if yes, can you check whether the content-type value is same on IE and FF?

OK, I downloaded Fiddler2, it shows my ICON as Content-Type: text/plain

when it should show it as Content-Type: image/x-icon

What do I need to change in the HTTP profile so that it recognizes it as image/x-icon ?

i do not think bigip changes the content-type header value. anyway, can you try something like this?

e.g.

[root@ve11a:Active:Not All Devices Synced] config  tmsh list ltm rule myrule
ltm rule myrule {
    when HTTP_REQUEST {
  if { [HTTP::uri] equals "/favicon.ico" } {
    set favicon 1
  } else {
    set favicon 0
  }
}
when HTTP_RESPONSE {
  if { $favicon and [HTTP::status] == 200 } {
    HTTP::header replace "Content-Type" "image/x-icon"
  }
}
}

Should I do something with Compression?

It is set to Disabled

I only see in the include list:

text/ application/(xml|x-javascript)

Should I enable it and put in image/x-icon ?

Just to level set, what happens when you completely disable compression?

It is set to Disabled under http profile

Also, what about Pipelning it is set to Enabled and Insert X-Forwarded-For is set to Enabled

All of this started to happen when I setup a custom HTTP profile.

I do see Contenet Compression is set to Content List - should I change that to Not Configured?

I just looked at the Fiddler Output again, and when it accesses /favicon.ico I now get: Content-Type: image/x-icon - weird - it just showed text/plain before...

I made no changes though......

And it still does not display the favicon.ico in the address bar...

If I setup that iRule that nitass suggested, could that fix it? or could it cause issues to live traffic if I enabled it for my VIP to try?

or is there something else I could try?

What about Response Chunking, it is set to Selective - should that be changed ? and Redirect Rewrite is set to None...

Maximum Header Size is 32768

And I disabled OneConnect Transformations.

I can clearly view the favicon.ico in any other browser, except for IE - it shows just garbage text, but in Firefox it shows the clean favicon.ico the way it is suppose to. Only IE is messed up....

I just looked at the Fiddler Output again, and when it accesses /favicon.ico I now get: Content-Type: image/x-icon - weird - it just showed text/plain before...

if favicon.ico is not shown in address bar even content-type is image/x-icon, the irule i gave will not help.

can you find out what different in fiddler between using http profile and not using http profile?

No difference.

I did apply your iRule.

With your iRule that is when it showed the favicon as image/x-icon when I remove your iRule is goes back to text/plain

When I use Fiddler WebView on /favicon.ico - I clearly see the ICON without any issues.

The only issue is in Internet Explorer only.

Is there some other work around?
