This proiblem was reported by Debbie Pagurek.  Using the context file at
http://wms1.agr.gc.ca/context_lakes.xml, all of the layers appears except for
the point layers.

The request fails with the following error in the Apache error_log:
[Mon Sep 29 15:08:01 2003].187837 HTTP: After download loop
[Mon Sep 29 15:08:01 2003].188536 HTTP: request failed with curl error code 47
(Maximum (10) redirects followed) for ...

(I took out the URL from the error message since it freezes bugzilla... odd!)

However the command-line version of curl is able to follow the redirection
(there is only one, not 10) and MapServer 4.0/4.1 which was used to reproduce
this is setup to follow redirections.

Trying to set the GetMapURL in the URL field since it freezes bugzilla when I
copy it to a comment.  :S

This is really odd... I can't upload the sample context attachment to bugzilla.

For the record, I was using libcurl 7.10.4 for my tests.

Resolution: → fixed
Status: new → closed 
It turns out that this was caused by a libcurl bug that has been fixed in
version 7.10.7.  From the libcurl 7.10.7 change log:

  - FOLLOWLOCATION (or -L) did not always ignore the redirect page properly

After upgrading libcurl to version 7.10.7 the layer works fine.

I will update the README.CONFIGURE docs to document the fact that 7.10.2 is
required, but 7.10.7 is strongly recommended.
