The webservice will then route these requests to a smart card</p> <p>When the system date changes, I want the following to happen.</p> <ol> <li><p>New request from the clients are made to wait</p></li> <li><p>Current work between webservice and smart card should get completed</p></li> <li><p>If there is any prior pending requests then they should get completed.</p></li> </ol> <p>The reason why I need the above things to happen is, I need to close the existing sessions between the smartcard and webservice. This should happen only when there is no signing/verification of files. I cannot just close all the sessions as it might affect a file being processed by any one of the threads. So I need to make sure that there are no current active threads between webservice and smart card.</p> <p>I wrote a piece of code which gives the total number of active threads between webservice and smartcard.</p> <pre><code>int vWorkerThreads,vWorkerThreadsMax; int vPortThreads,vPortThreadsMax; System::Threading::ThreadPool ^ vThreadPool; vThreadPool->GetAvailableThreads(vWorkerThreads, vPortThreads); vThreadPool->GetMaxThreads(vWorkerThreadsMax, vPortThreadsMax); ActiveThreadCount = vWorkerThreadsMax - vWorkerThreads; </code></pre> <p>This means, I also need to make the client requests wait?</p> <p>CLEANUP MECHANISM: Close the PKCS#11 API using <code>C_CloseAllSessions</code> and <code>C_Finalize</code> call which will free up the library so that it cleans all the session objects. This should be done once everyday.</p> <p>Any ideas on how I can perform such a task?</p> <p><strong>UPDATE:</strong></p> <p>I could have been much more clearer in my query. I want to make it clear that my aim is not to shutdown the ASP.NET webservice. <strong>My aim is to reset the smartcard</strong>. As I am accessing the smartcard via ASP.NET webservice, I need a mechanism to perform this task of resetting the smart card.</p> <p>I am giving the current process below</p> <blockquote> <ol> <li>Client detects Date change, At midnight</li> <li>Client calls the function <code>WebService_Close_SmartCard</code> </li> <li>Web Service receives the request <code>WebService_Close_SmartCard</code> and in turn calls <code>PKCS11_Close_SmartCard</code>. This Call will be served via one of the available threads from the Thread Pool. <code>PKCS11_Close_SmartCard will</code> close all the existing current sessions with the smartcard.</li> <li>At this point, I want to make sure that there are no threads with function calls such as <code>PKCS11_DigitalSign_SmartCard</code>/ <code>PKCS11_DigitalVerify_SmartCard</code> talking to smartcard, as <code>PKCS11_Close_SmartCard</code> will abruptly end the other ongoing sessions.</li> </ol> </blockquote> <p>PS: I am new to ASP.NET and Multithreading.</p>
