Question

Hi,

I just upgraded to version 4.2 and I'm using %INCLUDE% on one of the pages and getting this error:

Failed to include URL http://somesite.sun.come/test.html Incomplete headers

Anyone seen this before?

I even tried just using a simple .txt file.

Thanks,

Nam

There's an option in bin/configure named {INCLUDE}{AllowURLs} which you need to switch on. It is an "expert" option, so you need to click the "Yes, I've read all the documentation" button first.

The upgrade resets the config params, so this could be what happened.

Just spent hours banging my head against this error message. Another requirement (in addition to the above) is to make sure your CGI setup is correct. Personally, I find the TWiki setup uncomfortably vague in regard to what PERL modules are needed, and how to get them. A definitive list, or set of explicit instructions on how to set up PERL with the right modules would be great, but instead so far we only get hints like "Use your linux package manager" or "Use CPAN" but not explicit steps on HOW.

(Sorry to complain)

The solution was found by running twiki/bin/configure, logging in as administrator, clicking Configure, then clicking CGI Setup (read only). In there, down buried in the long list of required modules is the LWP module. THIS IS THE ONE THAT'S NEEDED! Note how it reads "needed for the Configure Extensions instsaller, and for external URL based INCLUDEs".

Which is what this error is about. Installing LWP (for me, using CPAN didn't make it show up in TWiki, I used synaptic package manager on Ubuntu and installed "libwww-perl" <- note the non-intuitive name vs. TWiki's generic name "LWP" (oops I complained again) ... in any case, this fixed the errors, and %INCLUDE with URLs in them works again!
