575324 - Case Sensitive to URLs of PNG images.

Status: RESOLVED INVALID

(Firefox :: File Handling, defect)

Description

[Jed]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.4) Gecko/20100611 Firefox/3.6.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.4) Gecko/20100611 Firefox/3.6.4

I have never noticed this issue until making the jump to Firefox 3.6.4 build 7.

When I login to my content management system, the logo it is to display is called "cms.png"

But in my webserver, it is actually called "CMS.png"

So, Firefox failed to display the image. When I corrected the case, it was fine!

I have had no problem before with this until this build of Firefox.

Reproducible: Always

Steps to Reproduce:
Go to a page that calls an image in this format <img src="http://www.example.com/abc.png" alt="abc">, but the image is actually located at http://www.example.com/ABC.png

Actual Results:  
Image does not load.

Expected Results:  
Image loads.

I feel that this is a major issue, as it has the potential to break the UIs of many websites.

Firefox is only sending text strings, its the server that decides if there should be case sensitivity or not. Firefox has nothing to do with it.

Apache example: http://httpd.apache.org/docs/1.3/misc/FAQ-H.html#rewrite-nocase
