Chrome block requests

Question

I am facing unusual issue in Chrome. it is blocking a few requests and returns following:

min.php?g=oxp-js&v=2.8.11 /openx/www/admin/assets GET (failed) dashboard.php:29 Parser

On further investigation it says:

Chrome provisional headers are shown

Same page works fine on other browsers.

Response Headers are given Below

Request URL:http://localhost/openx/www/admin/assets/min.php?g=oxp-css-ltr&v=2.8.11
Request Headers CAUTION: Provisional headers are shown.
Accept:text/css,*/*;q=0.1
Cache-Control:no-cache
Pragma:no-cache
Referer:http://localhost/openx/www/admin/dashboard.php

Query String Parametersview sourceview URL encoded
g:oxp-css-ltr
v:2.8.11

Below is the Buggy LInk that is not executed well by Chrome when executed as a part of a web page

[link rel="stylesheet" type="text/css" href="http://localhost/openx/www/admin/assets/min.php?g=oxp-css-ltr&v=2.8.11]

But when I access directly, it returns Headers properly. I can't figure out why is it like that?.

Update

I used LIVE HTTPHEADERS extension to grab the content, given below:

Answer 1

I had a similar problem today loading jShowOff jQuery's plugin. In my case the resource was being blocked by a Chrome extension (AdBlock). I couldn't see the problem in other browsers because AdBloc was installed in Chrome only.

The CAUTION: Provisional headers are shown. message is shown in DevTools because the headers you are seeing are not the actual headers sent to the server. In this case no headers were sent, because the resource was blocked before doing the request. The comments in this issue has additional details that explain the CAUTION message.

You probably have an extension that's blocking your URL.

I ran into a similar issue this week. For few Chrome and Safari users, there was a huge delay in loading the web application. My application is based on Spring MVC framework and is deployed on Tomcat 7 server. I found that the issue was with server's HTTP Connector attibute : maxKeepAliveRequests.From the Tomcat's HTTP Connector documentation found here,I understood that this attribute determines the maximum number of HTTP requests which can be pipelined until the connection is closed by the server. In your case, I see the header attribute is set to "Keep-Alive: timeout=5, max=100". Please check the corresponding connector value in your server and take appropriate action.
