I'm using SimpleCaptcha to secure our contact form. It works well, but only after reloading the page.
The Servlet is nl.captcha.servlet.StickyCaptchaServlet
, so it should not change the image after reloads. But when first opening the page the image is just not loaded. However, after reloading everything works fine.
the web.xml
The captcha is served by an application running at /services
.
<web-app>
<servlet>
<servlet-name>captcha</servlet-name>
<servlet-class>nl.captcha.servlet.StickyCaptchaServlet<servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>captcha</servlet>
<url-pattern>/captcha.png</url-pattern>
</servlet-mapping>
</web-app>
the html
<img src="/services/captcha.png">
the server
I'm using tomcat-7.0.34
on a Windows 7 64bit
machine with Java 1.7.0_07
.
the question
Why does the image only show up after a reload? Any ideas?
Just do this way to by pass what emka86 had said.
Hope this helps for any future developer out there.
