The maximum message size quota Problem in wcf

If you are working on wcf rest service and getting below error:

The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.

Then there are two solutions.

1. Check your webconfig/Appconfig and Edit system.serviceModel section or check the below code:

please copy the below code and replace "♣" with '<' or '>'sign.

=================================================================

♣system.serviceModel♣

  ♣services♣

    ♣service behaviorConfiguration="TestServiceBehavior" name="TestWcfService.TestService"♣

      ♣endpoint address="" binding="webHttpBinding" contract="TestWcfService.ITestService" behaviorConfiguration="WebBehavior" bindingConfiguration="StreamedRequestWebBinding"♣

        ♣identity♣

          ♣dns value="localhost"/♣

        ♣/identity♣

      ♣/endpoint♣

      ♣endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/♣

    ♣/service♣

  ♣/services♣

  ♣bindings♣

    ♣webHttpBinding♣

      ♣binding name="StreamedRequestWebBinding" bypassProxyOnLocal="true" useDefaultWebProxy="false" maxReceivedMessageSize="2147483647"

               maxBufferSize="2147483647" maxBufferPoolSize="2147483647" transferMode="StreamedRequest"♣

        ♣readerQuotas maxStringContentLength = "2147483647" /♣

              contract="ServiceReference.IYourService" /♣

  ♣/client♣

        ♣webHttp/♣

      ♣/behavior♣

    ♣/endpointBehaviors♣

  ♣/behaviors♣

♣/system.serviceModel♣

2. If the problem is still there then 2nd way is by coding and the coding part is :

WebHttpBinding binding = new WebHttpBinding(WebHttpSecurityMode.None);

            binding.MaxBufferSize = Int32.MaxValue;

            binding.MaxBufferPoolSize = Int32.MaxValue;

            binding.MaxReceivedMessageSize = Int32.MaxValue;

            XmlDictionaryReaderQuotas readerQuotas = new XmlDictionaryReaderQuotas();

            readerQuotas.MaxStringContentLength = int.Parse("2147483647");

            readerQuotas.MaxArrayLength = int.Parse("2147483647");

            binding.ReaderQuotas = readerQuotas;

            using (WebChannelFactory<ITestService> cf = new WebChannelFactory<ITestService>(binding,new Uri(Convert.ToString(ConfigurationManager.AppSettings["ServiceUrl"]))))

            {

                ITestService channel = cf.CreateChannel(); 

                String result = channel.YOURMETHOD();

                Response.Write(result);

            }

Handle Session Timeout with JQUERY

Use below code copy and paste for testing: This code keep your session alive if you click on OK button when message pop show. but if you don't click on this button it by default redirect to again same page. So you didn't get session timeout issue again. I had get junk character when session timeout. I did everything e.g webconfig setting  to increase the session timeout and request timeout etc but didn't get any success but now everything is working fine. In the below code i highlighted the main code.

Step1: Put these script and css in the Title Tag

 <script type="text/javascript" src="JS/jquery-ui-1.8rc1.custom.min.js">script>

 <link rel="stylesheet" type="text/css" href="JS/jquery-ui-1.8rc1.custom.css" />

 <script type="text/javascript" src="JS/jquery.idletimer.js">script>

Step2: This is script. Write this code in script tag

 var idleTime = 3000; //60000; //1800000; // number of miliseconds until the user is considered idle

        var initialSessionTimeoutMessage = 'Your session will expire in  seconds.

Click on OK to continue your session.';

        var sessionTimeoutCountdownId = 'sessionTimeoutCountdown';

        var redirectAfter = 20; // number of seconds to wait before redirecting the user

        var redirectTo = window.location; // URL to relocate the user to once they have timed out

        //        here window.location is used because it set the current url

        var keepAliveURL = 'keepAlive.php'; // URL to call to keep the session alive

        var expiredMessage = 'Your session has expired.  You are being logged out for security reasons.'; // message to show user when the countdown reaches 0

        var running = false; // var to check if the countdown is running

        var timer; // reference to the setInterval timer so it can be stopped

        $(document).ready(function () {

            // create the warning window and set autoOpen to false

            var sessionTimeoutWarningDialog = $("#sessionTimeoutWarning");

            $(sessionTimeoutWarningDialog).html(initialSessionTimeoutMessage);

            $(sessionTimeoutWarningDialog).dialog({

                title: 'Session Expiration Warning',

                autoOpen: false, // set this to false so we can manually open it

                closeOnEscape: false,

                draggable: false,

                width: 460,

                minHeight: 50,

                modal: true,

                beforeclose: function () { // bind to beforeclose so if the user clicks on the "X" or escape to close the dialog, it will work too

                    // stop the timer

                    clearInterval(timer);

                    // stop countdown

                    running = false;

                    // ajax call to keep the server-side session alive

                    $.ajax({

                        url: keepAliveURL,

                        async: false

                    });

                },

                buttons: {

                    OK: function () {

                        // close dialog

                        $(this).dialog('close');

                    }

                },

                resizable: false,

                open: function () {

                    // scrollbar fix for IE

                    $('body').css('overflow', 'hidden');

                },

                close: function () {

                    // reset overflow

                    $('body').css('overflow', 'auto');

                }

            }); // end of dialog

            // start the idle timer

            $.idleTimer(idleTime);

            // bind to idleTimer's idle.idleTimer event

            $(document).bind("idle.idleTimer", function () {

                // if the user is idle and a countdown isn't already running

                if ($.data(document, 'idleTimer') === 'idle' && !running) {

                    var counter = redirectAfter;

                    running = true;

                    // intialisze timer

                    $('#' + sessionTimeoutCountdownId).html(redirectAfter);

                    // open dialog

                    $(sessionTimeoutWarningDialog).dialog('open');

                    // create a timer that runs every second

                    timer = setInterval(function () {

                        counter -= 1;

                        // if the counter is 0, redirect the user

                        if (counter === 0) {

                            $(sessionTimeoutWarningDialog).html(expiredMessage);

                            $(sessionTimeoutWarningDialog).dialog('disable');

                            window.location = redirectTo;

                        } else {

                            $('#' + sessionTimeoutCountdownId).html(counter);

                        };

                    }, 1000);

                };

            });

        });

Step3:Put this in before closing the body tag:

    div id="sessionTimeoutWarning" style="display: none">
