Good Morning
Im hoping someone could at least give metheir opinion on this theory. Seems
like it would work when I modeled it out.But I might be missing something.
I am using snippets from code that I found atCodeProject. The url to this
code is: http://www.codeproject.com/csharp/2WayConnection.asp
I will be referencing this code here.
What im thinking about doing is taking everything thats inthe Server app
(basically a Listener, but when sending it creates HTTP headersand body) and
creating an IIS Object out of it.
Here's how I think it could work:
(Before I get into this, the CLIENTB has a Firewall that’s Outbound Only)
IIS Object(from here on out is referenced as just IIS): Singleton, oninitialize
creates a listener thread(Just like the server app), waits forconnections
ClientA: Connects to IIS, IIS puts its CorrelationID(Possibly IP too) insidethe
Queue for later use.
For now lets say the CorrelationID for ClientA is 1.
ClientB: Connects to IIS, IIS puts its CorrelationID(Possibly IP too) insidethe
queue(NOTE: maybe not queue, but ArrayList) for later use.
ClientB's CorrelationID is 2.
Note that this queue, or ArrayList will hold the active Connection,
theconnection has not been closed at this time.
Im thinking by sending a package every few seconds it wouldkeep the connection
alive.
ClientA: Sends a ‘POST’ verb to IIS, the Body contains an
object[]that holds the information that I want IIS to send ClientB.
NOTE: Without having to download the code and seeing foryourself, the Body
property in this sample code is a Byte[], im hoping tochange that to an
Object[].
IIS: Receives the request, calls ProcessesRequest method, grabs the Body,
itthen parses the object[] and looks at the Index of it:
Index:
0: Verb that IIS is to use
1: The Remote IP that the command is going too
2: The Body that is to be sent to Remote IP
IIS: Then see's the Index[1]'s IP, Checks the queue, or ArrayList of
ActiveConnections and finds the Active Connection of the Remote IP(ClientB, ID2)
IIS: Then creates the Headers and everything it needs, sets the Body to
theobject[] found in Index[2] and Fires off the Verb found in Index[0].
Ok, hope this makes sense what im about to explain. If you are familiar
withHTTP (or SOAP) you know that it has a header and body.
The ‘Verb’ would be like “GET” or “POST”.
The ‘Body’ would be something like “HelloWorld” if it
was a string or any binary data you want to send.
The ‘Version’ would be “HTTP/1.1”
Make sense?
When the IIS Object gets the package from Client A, itwill open the Object[]
found in the Body and see what it is suppose to send toClientB
The Object[] would say something like this:
Object[] Index:
0: “POST”
1: 192.168.0.1 – ClientB’s IP
2: object[] – the Data to Send ClientB
When the IIS Object see’s this, it will create itsown http headers and
after finding the Active Connection in the CollectionsObject (ArrayList or
Queue)
It will do this:
HttpMessage req = new HttpMessage();
req.Verb = (string)Object[0];// the “GET” or “POST”
command
req.RequestUri ="/";
req.Version ="HTTP/1.1";
req.Headers["Sequence-Num"] = 1;
req.Body = Object[2]; //the data to send to Client B
//Send Async
IAsyncResult async =_conn.BeginSendMessage(req);
ClientB sees the incoming request, grabs the object[] inthe Body and processes
it.
This object array will be the commands that I want it to do,
like'GetFolderList' or something like that.
It then processes my command, packs the return in an object[] of its own.
Calls IIS and does the exact same process ClientA had to do to get the
packagehere.
Whew! Ok, does this sound like it would work?? Also, not knowing what
theoriginal data type is of the Body tag in Http, can I change the byte[]
toobject[]? That should be all im expecting to recieve in this Body, no
stringsor anything.
Active Connections? Right now I am using straight..Net Remoting with IIS and
after making the connection I place the object in aSortedList, I never have to
make another connection I just reference the objectin the SortedList.
Does this qualify as an Active Connection? Wouldthis work with tcp
connections?
I hope you was able to follow me through this. Please help if you can. I
ampulling at straws and need some more direction.
Have a great afternoon.
Steve
