My q is whats can stop http post from desktop applications ?
e.g
i have a desktop application before it start it's ask users form some information
like a username ad Email ,,, and then take this information and post it on php webpage and php insert it into MySql Server any way the problem now is lets say like
6 of 16 download(s) are registered and the others not so whats can make http post not run correctly ?
Note :
Software tested on every windows os and runs ok
Software run with all anti viruses programs ok
Software add port throw windows firewall ok
So whats can make http post not run correctly ?

There are many things that could stop communication between your application, and your database.
If the client has a firewall that requires authorisation for outbound requests.
If the client has to connect via a proxy server, and you application is not proxy aware
If your website fails to process your request (perhaps, if the MySql server is too busy to allow connections, etc.)
So, consider an end user behind a WebSense proxy that additionally allows administrators to filter out unwanted traffic. If your application is not proxy server aware, it will fail to connect; If your application is proxy aware, and whatever WebSense category you fall into is filtered for that client, it will also fail to connect.

I am trying to intercept HTTP requests sent via an application I have installed on my Windows 7 machine. I'm not sure what platform the application is built on, I just know that Fiddler isn't correctly intercepting anything that this program is sending/receiving. Requests through Chrome are intercepted fine.
Can Fiddler be set up as a proxy for ALL applications, and if so, how would I go about doing this? I have no control over the application code, it's just something I installed. It is a live bidding auction program which seems to mainly display HTML pages inside the application window.
Fiddler isn't correctly intercepting anything that this program is sending/receiving
That means the program is either firing requests to localhost (very unlikely), or ignoring the proxy settings for the current user (most likely). The latter also means this application won't function on a machine where a proxy connection is required in order to make HTTP calls to the outside.
The alternative would be to use a packet inspector like Wireshark, or to let the application be fixed to respect proxy settings, or to capture all HTTP requests originating from that machine on another level, for example the next router in your network.
I installed an ASP.net application on a windows Azure VM (IIS 7). SSL certificate is installed, configured and the application works correctly. I have removed Http binding and http endpoints.
The issue I am having is that if I use the cloudapp.net link (using https), the application still opens with a mismatched certificate.
What can I do to deny any user from opening my application using https://xx.cloudapp.net/x?
It seems really silly that people are saying this isn't the right place for this question, since some of the solutions could be code related. ie: In your application, check the host and if it's cloudapp.net, do a URL redirect.
There's a few different options here but it sounds like what you're looking for is just the ability to prevent someone from viewing the application using that URL.
What I would do is set up a site in IIS that uses Host Header resolution to look for xx.cloudapp.net. If that URL is recognized, do a redirect using the HTTP redirect settings to the https version of your app. Don't bind the SSL port to this site or you'll run into SSL errors like you showed above.
The other option is to leave it out entirely and simply use the Host Header resolution to filter out requests for your site. I suspect what you've done is assign all incoming requests to the only IP address on the system, which is why the xx.cloudapp.net is showing your app and the cert is failing.
This would cause xx.cloudapp.net to fail to show any site at all but I think that might be what you want to do anyway.
Good afternoon in my timezone.
I am developing a web appp in J2EE.
This web app is called and access inside a sharepoint portal.
When i enter through the sharepoint portal i can access my application, using chrome developes tools i can see all the HTTP traffic, and i see that the browsers sends a request to the following server that is where my app is running serverprd.enterprisename.com.
But when i use the command line in my windows 7 , to ping the machine(server) , for example :
ping serverprd.enterprisename.com it returns me the following message:
"Ping request could not find host serverprd.enterprisename.com"
I am using a proxy.
Can anyone tells me why this happening ? Why through the browser i can access the server and the ping command does not find me the server ?
With the best regards.
Thanks in advance.
Your proxy server id the one who have an access to outside world. All http requests are sent to proxy server and proxy server does DNS lookup. In case of pin, your host have to do DNS lookup and this operation obviously now allowed ( firewall or so).
i've been searching and trying for weeks now to find a solution to my issue that I can understand and easily implement but I had no joy. So i would be very grateful if someone could put me out of my misery.
I'm building an iphone app similar in functionality to apps like "Air Video" and "Air Playit". The app should communicate with a server running on a remote host. This server should be able to execute a command sent by the iphone to encode a video and stream it over http.
In my case, my iphone app sends commands to be executed on a remote host. the remote host is running a python socket server listening for example on port 3333.
On the iphone, i'm simply using
"CFStreamCreatePairWithSocketToHost", "CFWriteStreamOpen" and
"CFReadStreamOpen"
to connect, write and read data.
My remote host, successfully intercepts the commands and starts the encoding.
To serve the contents, I'm having to run a separate http server (i'm using Python simpleHTTPServer) which is listening on another port.
What I would like to do is use the same port for both system commands and http requests.
The apps I've mentioned above seem to do it that way and I've noticed they have their own build-in web server.
I'm sure I'm missing something but please bear with me this is my first attempt at building an app.
Encode your system commands into special HTTP requests. Decide which thing to do (execute command or serve the contents) based on HTTP request, not on the incoming port. If you need to use separate http servers (like you told), consider having a layer that receives everything from the devices and dispatches to other servers (or ports) based on the request.
We have a web site that we have moved to LDAP authentication. But we are getting many "server not available" LDAP errors, even though the LDAP server remains in service. Do I need to worry about multiple users, each in their own thread causing concurrent authentication requests to the LDAP server and or causing too much authentication traffic for the LDAP server?. Does an (OSI) application accept multiple connections on the same incoming port at the same time or does it have to process them sequentially? Does it accept multiple connections from the same client (my web server) at the same time? If either of these are concerns, how do I architect my solution to overcome them? Should I be creating an single authentication object that is attached to the application object? Or is it o.k. to create it in each individual session/thread?
The FirstClass email system can provide LDAP services on port 389 out the 'front' of the application, and out the back, it can retrieve data from a different LDAP server.
What I would suggest is find out if there is a back end LDAP server and ask for permission to use that directly instead of proxying through FirstClass.
Man its been a while since I last saw FirstClass! Good to see they are still around!
