Tomcat Redirect breaks Alfresco Download in IE

norgan — Thu, 13 Nov 2008 13:33:53 GMT

Good day,I have a Tomcat Redirect : "For all Port 80 Requests, go to Port 443". This breaks the download function in Alfresco, when the user uses IE to access the HTTP Site.Example : Word (*.doc) can open or download in Firefox 3.0 allright. When I open the same http site with the same user via IE 6

Hi there,
I found the reason, but not the fix :

I made following change to the system :
I inserted a "security-constraint" forward for url "*" in the tomcat/conf/web.xml

/<security-constraint>
     <web-resource-collection>
        <web-resource-name>Protected Context</web-resource-name>
          <url-pattern>/*</url-pattern>
     </web-resource-collection>
  <!– auth-constraint goes here if you requre authentication –>
     <user-data-constraint>
        <transport-guarantee>CONFIDENTIAL</transport-guarantee>
     </user-data-constraint>
</security-constraint>/ ‍‍‍‍‍‍‍‍‍‍

reason : I wanted all http queries to be forwarded to https to force the usage of https
Effect : The IE 7.0, Word, Excel and probably others, could no longer download any Office files from alfresco. A download via Firefox 3.0 works fine.

The moment I removed that securityconstraint again, all was fine.

Question : Does anyone have a tipp, what went wrong and how to reach my goal anyway ? (No, I cant forbid the usage of IE )

server.xml :

    <Connector port="80" URIEncoding="UTF-8" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

Hi,

We have exactly the same problem as you describe.
Do you know of any solution or workaround for this yet?

Hi,

We were facing the same issue and we resolved it by configuring JBoss (Tomcat should not be different) adding following line :

<Valve className="org.apache.catalina.authenticator.FormAuthenticator" disableProxyCaching="false" />

in context.xml (server/alfresco/deploy/jboss-web.deployer) before </Context>

This website put me on the right way : http://confluence.atlassian.com/display/DOC/Adding+SSL+for+Secure+Logins+and+Page+Security

Downloading office documents is now working 😉

Pay attention to the fact that the Authenticator can be different the one we used, FormAuthenticator is specific to our external Authentication mechanism.
