Forum OpenACS Development: Re: Problems with SuppressHttpPort

Posted by Raul Rodriguez on

Yes I have OpenACS 5.9.1 installed following said installation.

After running OpenACS installation script I navigated to it via Firefox:

  • I entered the setup information and restarted the server.
  • A screen came up with a list of Applications and Subsites.
  • logged on to it and got a certificate via letscencrypt per README
  • At Main Site Parameters restricted site to ssl via set RestrictToSSL using '*'
  • in acs-tcl set SuppressHttpPort 1
  • Restarted OACS
  • Went to from another browser (Chrome) that had never gone to the site.
  • Chrome showed url with port

I verified that util_current_location is returning a result with no port as expected.

The port is added at some point later. I think this is happening in rp_filter via security::redirect_to_secure via security::get_secure_location where join_location is called.

Dear Raul, many thanks for the good report!

So, the problem is probably the upgrade to secure, i.e. when connecting via HTTP to a site requiring HTTPS , having SuppressHttpPort set. Can you apply the change [1] to your installation and check whether this helps? If so, i'll do the same change on HEAD and add some test cases.

all the best

I applied the patch and works as expected. Going to returns with no port.

Thank you

I've updated the oacs-5-9 branch, increased version number and re-tagged, such that OpenACS 5.9 users can also do a "upgrade from repository".

In the HEAD branch, i did similar (did some more cleanup, including a small regression test, ...)

all the best

Went to

The "ACS Site-Wide Administration" link has the port,

Does the logic need to be updated to include a check for SuppressHttpPort?

The link uses util::configured_location

    Return the configured location as configured for the current
    network driver. While [util_current_location] honors the virtual
    host information of the host header field,
    util::configured_location returns the main configured location
    (probably the main subsite). This also differs from [ad_url],
    which returns always the same value from the kernel parameter,
    since it returns either the https or http result.

    @return the configured location in the form "proto://hostname?:port?"

    @see ad_url
    @see util_current_location
