    <body bgcolor="white">

            <span><H1>Server Error in '/MyPortal' Application.<hr width=100% size=1 color=silver></H1>

            <h2> <i>Runtime Error</i> </h2></span>

            <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">

            <b> Description: </b>An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
            <br><br>

            <b>Details:</b> To enable the details of this specific error message to be viewable on remote machines, please create a &lt;customErrors&gt; tag within a &quot;web.config&quot; configuration file located in the root directory of the current web application. This &lt;customErrors&gt; tag should then have its &quot;mode&quot; attribute set to &quot;Off&quot;.<br><br>

            <table width=100% bgcolor="#ffffcc">
               <tr>
                  <td>
                      <code><pre>

&lt;!-- Web.Config Configuration File --&gt;

&lt;configuration&gt;
    &lt;system.web&gt;
        &lt;customErrors mode=&quot;Off&quot;/&gt;
    &lt;/system.web&gt;
&lt;/configuration&gt;</pre></code>

                  </td>
               </tr>
            </table>

            <br>

            <b>Notes:</b> The current error page you are seeing can be replaced by a custom error page by modifying the &quot;defaultRedirect&quot; attribute of the application&#39;s &lt;customErrors&gt; configuration tag to point to a custom error page URL.<br><br>

            <table width=100% bgcolor="#ffffcc">
               <tr>
                  <td>
                      <code><pre>

&lt;!-- Web.Config Configuration File --&gt;

&lt;configuration&gt;
    &lt;system.web&gt;
        &lt;customErrors mode=&quot;RemoteOnly&quot; defaultRedirect=&quot;mycustompage.htm&quot;/&gt;
    &lt;/system.web&gt;
&lt;/configuration&gt;</pre></code>

                  </td>
               </tr>
            </table>

            <br>

Have you correlated VIEWSTATE and EVENTVALIDATION parameters? If not - you cannot have them hard-coded. You need to design your test case as follows:

  • GET Request to login page (user opens login page)
    • Extract "VIEWSTATE", "EVENTVALIDATION" and any other dynamic parameters into JMeter Variables
  • POST Request to login page (user enters credentials)
    • Provide previously extracted "VIEWSTATE" and "EVENTVALIDATION" variables values, login, password and any other parameters.

Depending on your skills and nature of response you can use the following Post Processors in order to extract dynamic values:
