[mapserver-users] URL redirection under Apache2-Difference WMS and WFS server

[Pasquale Regina]

Greetings to everyone on the user list.

Sorry for my english. 

I have a problem to submit because I cannot frame it properly: I do not
expect that you will solve it but you can provide guidance on how to deal
with it and I move on. 

According with mapserver wms server howto at
<http://mapserver.org/ogc/wms_server.html>
http://mapserver.org/ogc/wms_server.html, in section “Changing the Online
Resource URL” I follow the indication “Apache environment variables –
MS_MAPFILE”. So I create a link in http cgi-bin folder named mywms which
points to /usr/lib/cgi-bin/mapserv, the application/executable file.

My http.conf file contain instruction:

Alias /mywms /usr/lib/cgi-bin/mapserver

<Location /mywms>

SetHandler cgi-script

Options ExecCGI

SetEnv MS_MAPFILE
/var/www/biss.org/public_html/pmapper/config/default/pmapper_demo_wms.map

</Location>

And the application correctly works and in a wms gis client I can connect to
wms server with follow link  <http://www.biss.org/mywms> www.biss.org/mywms.

This is configuration to access to a single default mapfile
(pmapper_demo_wms.map).

In a similar way for a wfs server with pmapper_demo_wfs.map (mywfs link in
cgi-bin folder, 
)

 

My project manager wants to change the settings of project by create
individual mapfile (not only one, the default) for each registered user and
so I need  to access the individual mapfiles inserting different links: in
other words in a wms gis client I put the link
<http://www.biss.org/mywms_123_45> www.biss.org/mywms_123_45 to point to the
file pmapper_demo_wms_123_45.map (123_45 represents a registered user id,
one of actually 75 registered users!! So I don’t create 75 and on link
).
The map files are created automatically by the database on user’s
registration for both wms e wfs mapfile.

So I changed in http.conf toward rewrite rule solution (and remove
references to Alias /mywxx and <Location /mywxx> for both mywms and mywfs)

in

<Directory “
/public_html”>


.

RewriteEngine on

RewriteRule myw?(.)s(.*)$
/cgi-bin/mapserv?map=/var/www/biss.org/public_html/pmapper/config/default/pm
apper_demo_w$1s$2.map&SERVICE=W$1S&REQUEST=GetCapabilities&

</Directory>

So when I put http://www.biss.org/mywms_123_45 in QGIS --> add WMS layer it
works because point to
pmapper_demo_wms_123_45.map&SERVICE=WmS&REQUEST=GetCapabilities according to
$1=m and $2=_123_45 variables.

The problem arises with wfs request in QGIS à add WFS vector. Putting
http://www.biss.org/mywfs_123_45 QGIS (and other wfs client similar) sends
the response in attached “Il server WFS non supporta la versione WFS 1.0.0
oppure l’ URL è errato” (Italian language!!) while putting
http://www.biss.org/cgi-bin/mapserv?map=/var/www/biss.org/public_html/pmappe
r/config/default/pmapper_demo_wfs_123_45.map it works correctly (which
demonstrate that mapfile is ok! and in the layer properties I read correctly

&SERVICE=WFS&VERSION=1.0.0&REQ
.)

what it is due to the difference in behavior for mapserver when rewrite the
url? Is it a feature of wfs server?

Can you direct me?

Thanks in advance. Pasquale.

PS. Apache2 version 2.4.7 on Ubuntu 14.04 MapServer 6.4.1
