Re: [PHP] HTTP_ACCEPT - Reliabilty?

[Danny Shepherd]

Hi,

No, I wouldn't rely on it at all, I couldn't find a browser that *does* have
that mime-type in it's header! - Here's what IE6 sends :

Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/msword, */*
Accept-Language: en-gb
Accept-Encoding: gzip, deflate

Flash, along with a multitude of other plugins, is installed and working
fine.

FWIW, Mozilla 1.3a sends:

Accept:
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=
0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,*/*;q=0.1
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate,compress;q=0.9

Opera 7 sends:

Accept: text/html, image/png, image/jpeg, image/gif, image/x-xbitmap,
*/*;q=0.1
Accept-Language: en
Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0

Subject: [PHP] HTTP_ACCEPT - Reliabilty?


 I'm using Flash very often within websites. Like you know, sometimes the
 user doesn't have the Flash-plug-in so I was wandering if I could depend
 on this $_SERVER['HTTP_ACCEPT'] variable to look for shockwave-flash.
 If found, the visitor has Flash-plugging, if not, he doesn't.

 So my question really is, can I base my Flash-detection on this global
 variable or is too uncertain? (e.g. when the user is using Netscape,
 Opera etc., Linux, Mac etc.)

Danny is right. The reason you cannot depend on the Accept
header is that most browsers will include */* as an
acceptable type (which basically means the browser will
accept any type/subtype) and assign it the lowest quality
factor.

I cannot imagine a Web browser that will prefer Flash
(assigning it anything but the lowest quality factor);
maybe some Web developers should consider that when
designing user interfaces. :-)
