146904 - Stylesheet loads only if returned with HTTP header "Content-type: text/css"

Status: RESOLVED WORKSFORME

(Tech Evangelism Graveyard :: English US, defect)

Description

[Mars]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.0rc2)
Gecko/20020510
BuildID:    2002051005

When a Web page with a CSS stylesheet is requested from a server, Mozilla only
seems to parse the stylesheet if the server's "Content-type" HTTP Response
Header is set to "text/css".

This definitely seems like behavior to be appreciated, but it causes a number of
previously functioning sites (on misconfigured servers) to loose their visual
formatting in Mozilla (and Netscape 6).

What follows here is a partial transcript of an HTTP session where I confirmed
the "Content-type" header field for the CSS file is incorrect:
------------------------------
Trying 207.115.185.170...
Connected to www.bodhiyoga.com.
Escape character is '^]'.
GET /bodhiStyles.css HTTP/1.1
Host: bodhiyoga.com

HTTP/1.0 200 OK
Date: Fri, 24 May 2002 21:39:28 GMT
Server: WebSitePro/2.4.9
Accept-ranges: bytes
Content-type: application/octet-stream
Last-modified: Fri, 24 May 2002 21:16:36 GMT
Content-length: 4606
------------------------------

As you can see, the server is responding by sending the CSS file as
"Content-type: application/octet-stream" instead of the correct "Content-type:
text/css". This causes Mozilla ignore the file, because it does not think it is
receiving CSS!

All my other Web browsers (IE5, iCab, Opera) still parse the CSS stylesheet on
sites like this!

Could the Content-type checking be loosened up to allow the sites on these
misconfigured servers to function normally again?


Reproducible: Always
Steps to Reproduce:
1. go to http://www.bodhiyoga.com/ in a non-Mozilla, CSS-compliant browser
(perhaps IE5)
2. go to the same site in Mozilla
3. compare the two -- notice the complete lack of formatting in the
Mozilla-rendered version of the page!

Actual Results:  Mozilla did not load the CSS stylesheet

Expected Results:  Mozilla should have loaded and parsed the stylesheet

invalid

Mozilla can't render a application/octet-stream CSS files.
Mozilla just follows the standards

[Boris Zbarsky [:bzbarsky]]

Wow.  Talk about lack of useless information...

See http://mozilla.org/releases/mozilla1.0/#devel -- this behavior only happens 
on pages which are being rendered in "standards" mode.  The vast majority of 
pages will be unaffected.

Reopening this. We should evangelize the site.

This is still an open issue...

The behaviour will no longer show up at the URL I gave as an example
(http://www.BodhiYoga.com/), because I contacted the sysop of host and notified
them of the problem. They fixed their HTTP server config, so CSS files are now
sent as "Content-type: text/css".

>This is still an open issue...

Where is the problem ?
The page is fixed ! (The bug is in Tech evangelism because want to send a mail
to the webmaster to fix the page)

That mozilla ignores non text/css files is correct and will not fixed (invalid)

-> wfm again

My mistake...I am new to the colloquial meanings and purposes of things such as
"Tech Evangelism" here in Bugzilla...WORKSFORME makes sense :)
