UPDATE Could it be this: strict-transport-security: max-age=8640000; includeSubDomains? from curl below:
curl -I http://innovationbound.com **(notice that's my bare domain I'm curling)**
HTTP/1.1 301 Moved Permanently

So, I've got the weirdest bug. If I clear my cache (firefox and chrome) and then load my blog: blog.innovationbound.com, it loads fine. But, after that, if I type in the url, or click on a link to the blog, or any path within the blog, I get a connection timed out.
My blog is hosted at Tumblr, innovationbound.tumblr.com, I have a CNAME record that points blog.innovationbound.com and www.blog.innovationbound.com to tumblr's domains.tumblr.com site. That's how tumblr works that out apparently.
Aside from that, I have a node.js website up and running at innovationbound.com. I have some middleware that ensures everything goes through ssl, so anything that hits that server gets redirected to https://...
Now nothing should hit that server if the CNAME records are working alright.
One other note: there used to be a redirect (301) from the bare domain to the www subdomain (because ssl only applied to www). That has since changed cause ssl applies to both (woohoo!).
Now when blog.innovationbound.com doesn't load, the problem loading page error shows up with https://blog.innovationbound.com, which is not what I typed in the first place, or what any links to our blog say either.
Any help would rock!
The problem seems to be that your middleware is also redirecting blog.innovationbound.com to use SSL, but only in some browsers.
Browsing to innovationbound.tumblr.com, the response is:
HTTP/1.0 301 Moved Permanently
Location: http://blog.innovationbound.com/
Browsing to http://blog.innovationbound.com/ in Chrome and Firefox results in being redirected to https://blog.innovationbound.com/
Browsing to http://blog.innovationbound.com/ in Safari presents the page without using SSL.
There are 4 IPs returned for blog.innovationbound.com, none of which accept https connections:
blog.innovationbound.com is an alias for domains.tumblr.com.
domains.tumblr.com. 30 IN A 66.6.40.74
domains.tumblr.com. 30 IN A 66.6.40.75
domains.tumblr.com. 30 IN A 66.6.40.76
domains.tumblr.com. 30 IN A 66.6.40.81
I put a script tag on my html page, and run it on firefox, firebug tell me that the script is '302 Moved Temporarily',
but when I open that script in new tag on the browser, it's 200 ok(response conrrectly)~~
I saw that when 302 the server response a redirect page, here's the header:
Cache-Control max-age=2592000
Connection keep-alive
Content-Length 154
Content-Type text/html

Server nginx
if I put the script on other server(no error redirecting page settings), will not come across this question
Anyone met the same question with me?
I don't want to put the file on other server and have no permission to config this server.
Is there a solution to this?
Thanks a lot and forgive my poor English.
I am having extreme difficulty understanding what you are asking so I'm just making a guess. If a 302 has a cache control header on it that tells the browser that it's allowed to cache the redirected page, the browser may do so. For example, here's some documented improvements in IE 9 with respect to caching redirect pages: http://blogs.msdn.com/b/ie/archive/2010/07/14/caching-improvements-in-internet-explorer-9.aspx
I have a website with some css and images.
I pushed some changes about the css and images to live.
I open IE/Firefox and type the URL to my website and hit return.
Then nothing is updated. I saw the IE/FF is not even try to ask for update, so there is no 304 returned.
I have to F5 fresh to get new content, but my users may not do this.
Does anybody know what to do?
Thanks
What is your HTTP server? You'll need to have it set the Cache-Control: no-cache HTTP header to disable caching at all your users.
This is really confusing me, it just does not want to work. I did exactly like the walk-through on MSDN says and I still get Under Construction page everytime I browse to the domain (fisharwe.com). Ok enough with the nag, here's what I did:
In Visual Studio 2010, I right clicked the project name and chose Publish. I chose to publish to the File System and everything went okey. Then I used CuteFTP to upload the files to the httpdocs folder (Plesk control panel), the live support guy said this is supposed to be the public folder. Finally, I tried to open the site and still nothing shows up... All I get is:
The site you are trying to view does
not currently have a default page. It
may be in the process of being
upgraded and configured.
So what's going on?
Judging by the following response header i'm seeing returned on your domain it seems your running IIS6;
Content-Length 1433
Content-Type text/html
Content-Location http://fisharwe.com/iisstart.htm

Take a good look at this article by Phil Haacked, hope it's helpfull. He explains how to set up an mvc website on iis6
You need to configure the server to send all requests through ASP.Net.
I have a controller in MVC serving up images from a database.
EDIT: This still happens if I serve up a file over completely standard means in MVC.
Every time I request my image, Google Chrome also searches for my favicon.ico.
To avoid unnecessary discussions about other things "I should also care about" let us assume I do not care for caching whatsoever in this example and I shall always return HTTP response 200 with the file.
In my controller I return the following:
return File(fileBytes, contentType);
After inspecting Fiddler 2, the following response is generated:
HTTP/1.1 200 OK
Cache-Control: public
Content-Type: image/gif
ETag: oYu19wKo+KEHkyxZQ2WXAA==

X-Powered-By: ASP.NET
Date: Tue, 16 Jun 2009 18:48:45 GMT
Content-Length: 29344
By comparison, this is the response in Fiddler from Google when I request (for the first time) the Google logo:
HTTP/1.1 200 OK
Content-Type: image/gif
Last-Modified: Wed, 07 Jun 2006 19:42:34 GMT

Cache-Control: public, max-age=31536000
Server: gws
Content-Length: 8706
Age: 2
However, in Chrome after getting my image Chrome attempts to find my favicon.ico. It does not try this after requesting the Google logo.
Any ideas why this might be happening? From my understanding on HTML, the answer must be in the response header because surely that is all the client has to go on? Please correct me!
EDIT 2: It seems a lot of people have completely misunderstood the problem. The problem is not the lack of a favicon and the erroring requests in MVC - it's the problem of requesting a favicon when only an image is being loaded, with a content type of "IMAGE/JPEG", as opposed to a webpage with a content type of "TEXT/HTML"!!
This has nothing to do with MVC. I am using webforms with a custom built log service and I stumbled upon this post wondering why I had continuous 'File does not exist' errors in my logs. This is locally on my development machine, I have no favicon.ico files in my projects, and I have tried IE, Firefox and Google trying to see which browser is the guilty party.
Every request from Google Chrome to my apps makes a request for a favicon.ico. I had to start logging browser locally to determine that it was in fact googles browser that is the culprit. I'd contact google if it bothers you. I just wanted to make sure it wasn't some new trojan infecting my chrome.
The actual answer: It's a known, verified bug. *(recently fixed!... maybe?)
Looks like a known, longstanding issue with Chrome:
http://crbug.com/39402
If you want it fixed sooner, star the issue. More people starring the issue will likely increase its priority and possibly get it fixed faster.
****UPDATE 1***: As of May 15 of this year (2013)--four years after this question was asked--it looks like the issue has been fixed in version 29:
http://crbug.com/39402#c47
Feel free to undo all your hacks and workarounds. :]
****UPDATE 2 (2015-01)***: This is apparently still an issue for some users, according to the same issue link. :/
Do you have a favicon? If not, perhaps that's why Chrome is attempting to find it every time for your website. For google it already has the favicon cached.
one thing you could do is have MVC ignore any request for *.ico so that you don't get any exceptions while debugging.
Should be something like this:
routes.MapRoute("ignore-favicon", "{*path}", null, new {path = ".*/favicon\\.ico"});
That URL pattern matches everything, but then we constrain it to only match anything ending in favicon.ico. (I haven't tested this)
I ran into this problem a while back and got around it by ignoring the specific route by adding
routes.IgnoreRoute("{*favicon}", new { favicon = ".*/favicon\\.ico" });
into the RegisterRoutes method in Global.asax.
It appears for me that Chrome requests a favicon for its own tabs - I kept getting 404s (because my favicon is somwhere else and my pages know it) till I did some tests and realized it was Chrome making direct requests to the favicon file. No real fix except making a rewrite to the real file I guess
You can add something like this within your web.config file to make sure that the favicon.ico is cached on the client and is not being requested every time.
<location path="favicon.ico">
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Cache-Control" value="public, max-age=31536000" />
</customHeaders>
</httpProtocol>
</system.webServer>
</location>
You can/should do the same for any images / .js and css files
You should set the Expires header to tell the browser how long it should use its local copy.
If you check your project setting it says default icon somewhere. Remove that?
Chrome browser could work with Google site in another way than with any other site, so, at first, I would recommend to check if it looks for favicon.ico every time somewhere else, for example, on StackOverflow.
I would also check if Firefox does the same with your site. I think favicon.ico should be requested only one time per browser run even if it isn't present on site. This could be bug in Chrome version you use.
This SO question/answer explains how to serve the Favicon to the browser by using routes.
Its important to put in an ICON link into your masterpage or some browsers will try to find favicon.ico for all directories and not just globally once per done.
<link rel="SHORTCUT ICON" href="<%= Url.Content("~/content/images/rr-favicon.ico") %>"/>
It seems google toolbar is the guilty party judging by my logs (and IE6 of course). They both will make requests for directories other than the root
