768563 - Some responses to /en-US/ have a reference to a 404 modernizr-2.5.0.min.js

Status: RESOLVED FIXED

(www.mozilla.org :: General, defect)

Description

[Ashish Vijayaram [:ashish]]

After the bedrock push in Bug 751730, Catchpoint alerted IT about 404 objects in https://www.mozilla.org/en-US/ Further troubleshooting led to one object - https://www.mozilla.org/media/js/libs/modernizr-2.5.0.min.js being referenced in the response.

A sample waterfall from Catchpoint is at http://p.catchpoint.com/ui/Entry/PW/V/CHN-KVH-t-YFQG-jPIdhyfVwA-AKfAZ19-C7Y0.Bfi-t

This looks to be some sort of a UA/lang-specific since requests via the browser don't repro the reference. The request headers from Catchpoint are:

GET /en-US/ HTTP/1.1
Accept: */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; Catchpoint)
Host: www.mozilla.org
Connection: Keep-Alive

I'm marking this major since this might reduce visibility of other alerts from the same check.

The requests from catchpoint and others has reduced to 0. While grepping through error logs, I found this interesting:

[Fri Jun 22 17:23:27 2012] [error] [client 10.8.81.216] File does not exist: /data/www/www.mozilla.org/[object, referer: http://www.mozilla.net/[object Object]&#173;<style>@font-face {font-family:"font";src:url("https://")}@media (touch-enabled),(-webkit-touch-enabled),(-moz-touch-enabled),(-o-touch-enabled),(-ms-touch-enabled),(modernizr){#touch{top:9px;position:absolute}}@media (transform-3d),(-webkit-transform-3d),(-moz-transform-3d),(-o-transform-3d),(-ms-transform-3d),(modernizr){#csstransforms3d{left:9px;position:absolute;height:3px;}}#generatedcontent:after{content:":)";visibility:hidden}</style>

Dropping severity down, since this isn't impacting anything now.

No longer issue and must have been a caching problem. Resolved now.
