  • Load balancing and sessions

    - by vtortola
    Hi there, What is the better approach for load balancing on web servers? My services run in .NET and Mono, so they could be hosted on IIS or Apache2, and the will have to provide SSL connection. I've read two main approaches, store the state in a common server and use sticky sessions, there is any other else? I've read 3 diffent things about sticky sessions: 1)the load balancing device will know with which server did you start the connection and all the further connections from that host will be routed to the same server. 2)the load balancing devide read a cookie named: JSESSIONID 3)the load balancing devide read a cookie named: ASPSESSIONID I'm a little bit confused, what will happen exactly? As the connections will be SSL there is not a chance for the load balancing devide of read the cookies, so then what? About store the estate in a common server, what solutions do you know? I've read memcache is a good solution but is there any other else? Cheers.

  • VS 2010 and Entity Framework: accessing SQL Server 2000 databases

    - by pcampbell
    Consider a Visual Studio 2010 project whose requirement is to model the data using Entity Framework. The datasource is a SQL Server 2000 database. The first step is creating a new ADO.NET Entity Data Model item. The Entity Data Model Wizard prompts for a Data Connection. When creating a new Connection, you will need to use a provider other than SqlClient. Usually it's SQLOLEDB. The list of data providers only has SqlClient or ".NET Framework Data Provider for SQL Server". Is there a work-around for Visual Studio 2010 to create or use data connections to SQL Server 2000 using the Entity Framework?

  • App.Config Ignored After Pre-Build Event

    - by Jake Hulse
    I have a solution with several projects and several developers, each with their own environment (of course). To manage connection strings between each environment, I have created several app.config files for each environment: app.config.dev, app.config.qa, etc. The pre-build event simply copies the app.config.$(ConfigurationName) to app.config. This pre-build event is done for each project in the solution, and the config string is included in each (including the test project). When I use the pre-build events to manage the app.config files, the connection string cannot be found. I can get the tests to run fine by 2 methods: 1. Do not use the pre-build events to manage the app.config file selection, and do it myself or 2. If I check out app.config and make it writable, then the pre-build events work just fine. We are using Visual Studio 2008. I'm down to my last grey hair here, any ideas? Thanks in advance!

  • C# connecting with RDP

    - by user311130
    |????| Hey, I want to connect to a remote desktop connection to a specified server/username from c#. I have found: _http://www.databaseforum.info/2/22/0a0e1d2da27798df.html a AxMSTSCLib dll should be referenced to the solution. I don't want to download this dll from anywhere as I'm not sure if I can trust it. However it also says: "After research on the web I found that I have to create new AxMSTSCLib and MSTSCLib DLLs. So I did" How do I "create" this new AxMSTSCLib ? Other link, doesn't use this dll but run an script instead. _http://bytes.com/topic/c-sharp/answers/517024-remote-desktop-connection-c but that code throws Security Exception. So I cannot use it. Thanks for any help |????|

  • c# Network Programming - HTTPWebRequest Scraping

    - by masterguru
    Hi, I am building a web scraping application. It should scrape a complex web site with concurrent HttpWebRequests from a single host to a single target web server. The application should run on Windows server 2008. One single HttpWebRequest for data could take from 1 minute to 4 minutes to complete (because of long running db operations) I should have at least 100 parallel requests to the target web server, but i have noticed that when i use more then 2-3 long-running requests i have big performance issues (request timeouts/hanging). How many concurrent requests can i have in this scenario from a single host to a single target web server? can i use Thread Pools in the application to run parallel HttpWebRequests to the server? will i have any issues with the default outbound HTTP connection/requests limits? what about Request timeouts when i reach outbound connection limits? what would be the best setup for my scenario? Any help would be appreciated. Thanks

  • WebKit "Refused to set unsafe header "content-length"

    - by Paul
    I am trying to implement simple xhr abstraction, and am getting this warning when trying to set the headers for a POST. I think it might have something to do with setting the headers in a separate js file, because when i set them in the <script> tag in the .html file, it worked fine. The POST request is working fine, but I get this warning, and am curious why. I get this warning for both content-length and connection headers, but only in WebKit browsers (Chrome 5 beta and Safari 4). In Firefox, I don't get any warnings, the Content-Length header is set to the correct value, but the Connection is set to keep-alive instead of close, which makes me think that it is also ignoring my setRequestHeader calls and generating it's own. I have not tried this code in IE. Here is the markup & code: test.html: <!DOCTYPE html> <html> <head> <script src="jsfile.js"></script> <script> var request = new Xhr('POST', 'script.php', true, 'data=somedata', function(data) { console.log(data.text); }); </script> </head> <body> </body> </html> jsfile.js: function Xhr(method, url, async, data, callback) { var x; if(window.XMLHttpRequest) { x = new XMLHttpRequest(); x.open(method, url, async); x.onreadystatechange = function() { if(x.readyState === 4) { if(x.status === 200) { var data = { text: x.responseText, xml: x.responseXML }; callback.call(this, data); } } } if(method.toLowerCase() === "post") { x.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); x.setRequestHeader("Content-Length", data.length); x.setRequestHeader("Connection", "close"); } x.send(data); } else { // ... implement IE code here ... } return x; }

  • Interfacing Android Nexus One with Arduino + BlueSmirf

    - by efgomez
    I'm a bit new to all of this, so bear with me - I'd really appreciate your help. I am trying to link the Android Nexus One with an arduino (Duemilanove) that is connected to a BlueSmirf. I have a program that is simply outputting the string "Hello Bluetooth" to whatever device the BlueSmirf is connected to. Here is the Arduino program: void setup(){ Serial.begin(115200); int i; } void loop(){Serial.print("Hello Bluetooth!"); delay(1000); } One my computer BT terminal I can see the message and connect no problem. The trouble is with my android code. I can connect to the device with android, but when I look at the log it is not displaying "Hello Bluetooth". Here is the debug log: 04-09 16:27:49.022: ERROR/BTArduino(17288): FireFly-2583 connected 04-09 16:27:49.022: ERROR/BTArduino(17288): STARTING TO CONNECT THE SOCKET 04-09 16:27:55.705: ERROR/BTArduino(17288): Received: 16 04-09 16:27:56.702: ERROR/BTArduino(17288): Received: 1 04-09 16:27:56.712: ERROR/BTArduino(17288): Received: 15 04-09 16:27:57.702: ERROR/BTArduino(17288): Received: 1 04-09 16:27:57.702: ERROR/BTArduino(17288): Received: 15 04-09 16:27:58.704: ERROR/BTArduino(17288): Received: 1 04-09 16:27:58.704: ERROR/BTArduino(17288): Received: 15 ect... Here is the code, I'm trying to put only the relative code but if you need more please let me know: private class ConnectThread extends Thread { private final BluetoothSocket mySocket; private final BluetoothDevice myDevice; public ConnectThread(BluetoothDevice device) { myDevice = device; BluetoothSocket tmp = null; try { tmp = device.createRfcommSocketToServiceRecord(MY_UUID); } catch (IOException e) { Log.e(TAG, "CONNECTION IN THREAD DIDNT WORK"); } mySocket = tmp; } public void run() { Log.e(TAG, "STARTING TO CONNECT THE SOCKET"); InputStream inStream = null; boolean run = false; //...More Connection code here... The more relative code is here: byte[] buffer = new byte[1024]; int bytes; // handle Connection try { inStream = mySocket.getInputStream(); while (run) { try { bytes = inStream.read(buffer); Log.e(TAG, "Received: " + bytes); } catch (IOException e3) { Log.e(TAG, "disconnected"); } } I am reading bytes = inStream.read(buffer). I know bytes is an integer, so I tried sending integers over bluetooth because "bytes" was an integer but it still didn't make sense. It almost appears that is sending incorrect baud rate. Could this be true? Any help would be appreciated. Thank you very much.

  • How to create an Entity Framework model from an existing SQLite database in Visual Studio 2008?

    - by splattne
    I've installed the System.Data.SQLite ADO.NET Provider from http://sqlite.phxsoftware.com/. I can connect to the database from within Visual Studio, I can open table schemas, views etc. I'd like to use an existing SQLite database to create an Entity Framework model in Visual Studio 2008. When I try to create a new ADO.NET Entity Data Model (.edmx) file using the wizard, the existing SQLite connection is not in the list though. Also, it's not possible to create a SQLite connection because there is no provider for SQLite. It only lists SQL Server, SQL Server file and SQL Server Compact 3.5. Any idea how to solve this problem?

  • How do I get autotest (ZenTest) to see my namespaced stuff?

    - by Blaine LaFreniere
    Autotest is supposed to map my tests to a class, I believe. When I have class Foo and class FooTest, autotest should see FooTest and say, "Hey, this test corresponds to the unit Foo, so I'll look for changes there and re-run tests when changes occur." And that works, however... When I have Foo::Bar and Foo::BarTest, autotest doesn't seem to make the connection, and whenever I edit Foo::Bar, autotest does not re-run Foo::BarTest Am I doing something wrong? EDIT: File structure might be helpful. Here it is: Module and class files: lib/foo.rb lib/foo/bar.rb lib/foo/baz.rb Test files: test/unit/foo/bar.rb test/unit/baz.rb I would think that autotest is able to make the connection between Foo::Bar and Foo::BarTest, but apparently it doesn't.

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too.

  • How do I use Google protobuf to communicate over a serial port?

    - by rob
    I'm working on a project that uses RXTX and protobuf to communicate with an application on a development board and I've been running into issues which implies that I'm likely doing things the wrong way. Here's what I currently have for writing the request to the board (the read code is similar): public void write(CableCommandRequest request, OutputStream out) { CodedOutputStream outStream = CodedOutputStream.newInstance(out); request.writeTo(outStreatm); outStream.flush(); } The OutputStream that is used is prepared by RXTX and the development board seems to indicate that data is being received, but it is getting garbled or is otherwise not being understood. There seems to be little documentation on using protobuf over a serial connection so I'm assuming that passing the OutputStream should be sufficient. Is this in fact correct, or is this the wrong way of sending the response over the serial connection?

  • Difference between Setting.settings and web.config?

    - by Muneeb
    This might sound a bit dumb. I always had this impression that web.config should store all settings which are suspect to change post-build and setting.settings should have the one which may change pre-build. but I have seen projects which had like connection string in setting.settings. Connection Strings should always been in web.config, shouldnt it? I am interested in a design perspective answer. Just a bit of background: My current scenario is that I am developing a web application with all the three tiers abstracted in three separate visual studio projects thus every tier has its own .settings and .config file.

  • Why Won't the WebSocket.onmessage Event Fire?

    - by SumWon
    Hey guys, After toying around with this for hours, I simply cannot find a solution. I'm working on a WebSocket server using "node.js" for a canvas based online game I'm developing. My game can connect to the server just fine, it accepts the handshake and can even send messages to the server. However, when the server responds to the client, the client doesn't get the message. No errors, nothing, it just sits there peacefully. I've ripped apart my code, trying everything I could think of to fix this, but alas, nothing. Here's a stripped copy of my server code. As I said before, the handshake works fine, the server receives data fine, but sending data back to the client does not. var sys = require('sys'), net = require('net'); var server = net.createServer(function (stream) { stream.setEncoding('utf8'); var shaken = 0; stream.addListener('connect', function () { sys.puts("New connection from: "+stream.remoteAddress); }); stream.addListener('data', function (data) { if (!shaken) { sys.puts("Handshaking..."); //Send handshake: stream.write( "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+ "Upgrade: WebSocket\r\n"+ "Connection: Upgrade\r\n"+ "WebSocket-Origin: http://192.168.1.113\r\n"+ "WebSocket-Location: ws://192.168.1.71:7070/\r\n\r\n"); shaken=1; sys.puts("Handshaking complete."); } else { //Message received, respond with 'testMessage' var d = "testMessage"; var m = '\u0000' + d + '\uffff'; sys.puts("Sending '"+m+"' to client"); var result = stream.write(m, "utf8"); sys.puts(result); /* Result comes as true, meaning that it pushed the data out. Why isn't the client seeing it?!? */ } }); stream.addListener('end', function () { sys.puts("Connection closed!"); stream.end(); }); }); server.listen(7070); sys.puts("Server Started!");

  • aspnet membeship logon page and https redirect

    - by DefSol
    Hello, I have a gridview control that has on onclick event bound to every cell. Once a user clicks on a cell it directs them to a booking confirmation page and passes 3 url variables. This booking page is behind a aspnet membership and thus if the user is not logged in they are served the login page. The login page has a redirect to https connection in the onload event using the IsSecure property. The issue is once the user logs in, then is returned to the booking confirmation page I lose 2 of the url vars. If I remove the https redirect, everything works fine, but the user logs on on a http connection, which is not cool. Appreciate and help thanks Reuben

  • using Spring JdbcTemplate for multiple database operations

    - by Joel Carranza
    I like the apparent simplicity of JdbcTemplate but am a little confused as to how it works. It appears that each operation (query() or update()) fetches a connection from a datasource and closes it. Beautiful, but how do you perform multiple SQL queries within the same connection? I might want to perform multiple operations in sequence (for example SELECT followed by an INSERT followed by a commit) or I might want to perform nested queries (SELECT and then perform a second SELECT based on result of each row). How do I do that with JdbcTemplate. Am I using the right class?

  • MySql timeouts - Should I set autoReconnect=true in Spring application?

    - by George
    After periods of inactivity on my website (Using Spring 2.5 and MySql), I get the following error: org.springframework.dao.RecoverableDataAccessException: The last packet sent successfully to the server was 52,847,830 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. According to this question, and the linked bug, I shouldn't just set autoReconnect=true. Does this mean I have to catch this exception on any queries I do and then retry the transaction? Should that logic be in the data access layer, or the model layer? Is there an easy way to handle this instead of wrapping every single query to catch this?

  • How to determine MS Access field size via OleDb

    - by Andy
    The existing application is in C#. During startup the application calls a virtual method to make changes to the database (for example a new revision may need to calculate a new field or something). An open OleDb connection is passed into the method. I need to change a field width. The ALTER TABLE statement is working fine. But I would like to avoid executing the ALTER TABLE statement if the field is already the appropriate size. Is there a way to determine the size of an MS Access field using the same OleDb connection?

  • NSMutableURLRequest not obeying my timeoutInterval

    - by kubi
    I'm POST'ing a small image, so i'd like the timeout interval to be short. If the image doesn't send in a few seconds, it's probably never going to send. For some unknown reason my NSURLConnection is never failing, no matter how short I set the timeoutInterval. // Create the URL request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:0.00000001]; /* Populate the request, this part works fine */ [NSURLConnection connectionWithRequest:request delegate:self]; I have a breakpoint set on - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error but it's never being triggered. My images continue to be posted just fine, they're showing up on Tumblr despite the tiny timeoutInterval.

  • NodeJS and node-mongodb-native

    - by w1nk
    Just getting started with node, and trying to get the mongo driver to work. I've got my connection set up, and oddly I can insert things just fine, however calling find on a collection produces craziness. var db = new mongo.Db('things', new mongo.Server('192.168.2.6',mongo.Connection.DEFAULT_PORT, {}), {}); db.open(function(err, db) { db.collection('things', function(err, collection) { // collection.insert(row); collection.find({}, null, function(err, cursor) { cursor.each(function(err, doc) { sys.puts(sys.inspect(doc,true)); }); }); }); }); If I uncomment the insert and comment out the find, it works a treat. The inverse unfortunately doesn't hold, I receive this error: collection.find({}, null, function(err, cursor) { ^ TypeError: Cannot call method 'find' of null I'm sure I'm doing something silly, but for the life of me I can't find it...
