i'm developing an application for blackbery, i'm displaying a webpage using Eclipse and net.rim.device.api.browser.field.* api when i click a submit buttom in a form i get this error "Unknown host http:80", can anyone helpme?
Don't know anything about Blackberries, but it looks like you're entering a URL where your program is only expecting a host name.
It sounds like form on the web page is not properly set up, causing the post action to post to an invalid URL. It would help if you included the app code and the form HTML.
In this 2005 forum thread people complain about getting that kind of error on their Blackberries.
I'm on the server side and I can see some Proxy servers trying to access my server with either HTTP/1.0 and no HTTP_HOST (which my app requires) or using the wrong HTTP_HOST.
For example, I am getting requests for widgets.twimg.com , www.google-analytics.com , servedby.jumpdisplay.com . My server doesn't host those domains so the response is obviously not any of the sites on the server, and instead I'm giving back an error.
So, it might be that your Blackberry is not providing the right HTTP_HOST to the server (or none at all) and the server doesn't know what to do with it.
To me, that's Blackberry (or whatever proxy that might exist between you and the server) 's fault.

Please consider the following two websites that I am pinging as shown in the image below:
I have a google plus login icon where a user can click on it and can sign in using his/her google account.
My website where all the login code is residing is say for example xyztesting.com as shown in the image. And all the code related to xyztesting.com resides on the box 10.11.10.12 which has a domain name abctesting.com.
So, when i ping abctesting.com, I get Packets Sent and Received = 4 as shown in the image.
However, when I ping xyztesting.com , I get Request timed out as shown in the image below.
Does anyone knows whether this could be the reason behind why I am getting Redirect URI Mismatch error 400 error whenever a user tries to log in using google plus ?
I have ensured that the REDIRECt URI in the request matches the Registered Redirect URIs which is the most common message displayed when some one encounters this error and this is the most common fix suggested online everywhere.
I have referred to lot of previous related posts, including this one where they talks about making sure that the request URI's should match the registered URI on google developer console.
I have got a feeling that since there is not a dedicated box/server for my website xyztesting.com, google is thowing such error. Please let me know if anyone has experienced such type of error with the situation I have described above?
Sometimes, the redirect uri should be set to "postmessage" not the actual uri.
The documentation is not so clear on that setting.

I see that this question has been asked before but no solution has been provided.
I am getting nothing but 500 Internal Server Error since yesterday when I use following link:
http://apps.facebook.com/myappID
Yes, I already tried clearing up my cache & cookies so don't even bother asking me this. I have added my app link in the Canvas URL which should show up after I click on the app URL but nothing but that 500 HTTP error. I tried on all browsers and even asked few of my friends too and they said same error.
I thought it was an error on Facebook but I don't see how it's not being fixed for a day now.
Any help? Thank you.
The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server but the server could not be more specific on what the exact problem is.
So its a "server-side" error, meaning the problem is not with your PC or Internet connection but instead is a problem with the web site's server.
Maybe you should contact facebook help center.
I just ran into a similar situation and found that when I reduced the limit in my GET call to 20 rather than 500 the server responded well.
https://graph.facebook.com/v2.0/6558867050/posts?limit=20
I have just set up a custom tab on my page for the first time. I have thoroughly followed the setup guide and seem to have everything on the Facebook side setup correctly.
However when I view my page it throws the following error:
Method Not Allowed The requested method GET is not allowed for the
URL /Facebook/index.html. Additionally, a 404 Not Found error was
encountered while trying to use an ErrorDocument to handle the
request. Apache/1.3.41 Server at feebnaturals.com.au Port 80
I believe it may be some kind of Apache server config issue, however I'm not that Apache savvy, so not sure where to start.
I had the same problem, but instead of GET, it was POST method which was not allowed. This is a setting on your server. Not server savvy myself, but it seems that my provider didn't allow this method on html-page, but makes no problem on doing the same for php-pages. So all I did was rename my page from .html to .php, updated the app settings in facebook and all works fine now.
This is definitely an error on your side, check your server logs and see what they say - it looks like you've configured the page to only work via a POST request and it's being requested in a GET request
I need to include some secure (BASIC authentication) application.
when I open the application URL in the browser, the browser asks me to enter your credentials ...
what I know is that:
The browser ask the server to get
some URL -- the url of the app
The server checks the request header
for the Authentication header and
didn't find it
The server sends 401 to the
browser back
The browser interpret this response
code into a message dialog that
shows to me asking me to enter the
username/password to send back to
the server in the Authentication
request header
So far... so good, I can write some page (in JSP) that send this required http request header to the request that is calling this page..
So I'll call this application through my page..
The problem here is, this application (in fact a GWT application) contains a reference to some Javascript and CSS files that is coming from the server that hosts this application. the application page that I import looks like:
<html>
<link href="http://application_host/cssfile.css" />
<link href="http://application_host/javascriptfile.js" />
.....
</html>
So, again I found the application asks me for the authentication crenditals for the css and js files!
I am thinking of many solutions but don't know the applicability of each
One solution is to ask the browser
(via Javascript) to send the request
header (Authentication) when he
asks the server for the js and css
files
please give me your opinions about that... and any other suggestions will be very welcomed.
Thanks.
I think you're running into some weirdness with how your server is configured. Authentication happens in context of a authentication realm. Your assets should either be in the same authentication realm as your page, or (more likely) should not require authentication at all. The browser should be caching credentials for the given realm, and not prompt for them again.
See the protocol example on http://en.wikipedia.org/wiki/Basic_access_authentication
Judging from your story, something tells me your problem is with the authentication method itsef. Not how to implement it. Why do you want to bother with the request header so much?
As far as i know, you can configure your container (ie Tomcat) to force http authentication for certain urls. Your container will make sure that authentication has taken place. No need to set http headers yourself whatsoever.
Perhaps you can explain a bit better what you are trying to achieve, instead of telling implementation details?
Why css & js files are kept in protected area of server? You need to place files into public area of your server. If you don't have public area, so you nead to prpvide for it. how to do it depends from serverside software architecture & configuration.
Why does using Fiddler break my site sometimes on page transitions.
After a server side redirect -- in the http response (as found in Fiddler) I get this:
Object moved
Object moved to here.
The site is an ASP.NET 1.1 / VB.NET 1.1 [sic] site.
Why doesnt Fiddler just go there for me? i dont get it.
I'm fine with this issue when developing but I'm worried that other proxy servers might cause this issue for 'real customers'. Im not even clear exactly what is going on.
That's actually what Response.Redirect does. It sends a 302 - Object moved response to the user-agent. The user-agent then automatically goes to the URL specified in the 302 response. If you need a real server-side redirect without round-tripping to the client, try Server.Transfer.
If you merely constructed the request using the request builder, you're not going to see Fiddler automatically follow the returned redirect.
In contrast, if you are using IE or another browser, it will generally check the redirect header and follow it.
For IE specifically, I believe there's a timing corner case where the browser will fail to follow the redirect in obscure situations. You can often fix this by clicking Tools / Fiddler Options, and enabling both the "Server" and "Client" socket reuse settings.
Thanks user15310, it works with Server.Transfer
Server.Transfer("newpage.aspx", true);
Firstly, transferring to another page using Server.Transfer conserves server resources. Instead of telling the browser to redirect, it simply changes the "focus" on the Web server and transfers the request. This means you don't get quite as many HTTP requests coming through, which therefore eases the pressure on your Web server and makes your applications run faster.
But watch out: because the "transfer" process can work on only those sites running on the server, you can't use Server.Transfer to send the user to an external site. Only Response.Redirect can do that.
Secondly, Server.Transfer maintains the original URL in the browser. This can really help streamline data entry techniques, although it may make for confusion when debugging.
That's not all: The Server.Transfer method also has a second parameter—"preserveForm". If you set this to True, using a statement such as Server.Transfer("WebForm2.aspx", True), the existing query string and any form variables will still be available to the page you are transferring to.
