title: Thymeleaf does not allow "lt" as query string parameter name
body: <p>I cannot use "lt" as query string parameter name in thymeleaf. How can I achieve that?</p>
  
  <p>This is my example code:</p>
  
  <pre><code>&lt;a th:href="@{/payment/otp-resend(lt=${landingToken.sessionId})}" class="sifretekrar" th:text="#{lp.resendOtp}"&gt;&lt;/a&gt;
  </code></pre>
  
  <p>And it gives the following error:</p>
  
  <pre><code>org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "@{/payment/otp-resend(lt=${landingToken.sessionId})}" (template: "otp-entry-page" - line 70, col 12)

  <p>Best regards.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>The accepted answer is correct. However, Intellij IDEA shows it as if it has an error. The screenshot is attached below. The following two lines are working while IDE displays error message for both of them:</p>
  
  <pre><code>&lt;a th:href="@{/payment/mps-otp-resend} + '?lt=' + ${landingToken.sessionId}" class="sifretekrar" th:text="#{lp.resendOtp}"&gt;&lt;/a&gt;
  
  &lt;a th:href="@{/payment/mps-otp-resend('lt'=${landingToken.sessionId})}" class="sifretekrar" th:text="#{lp.resendOtp}"&gt;&lt;/a&gt;
  </code></pre>
