Is it possible to automatically go back to the list view in summary mode after submitting a new message instead of displaying the new message?

I know it's possible to display a page from a file after submitting a new message  by using "Submit Page = <file>". 
It would be nice to be able to use a command like "Submit Page = <command>" where I could insert "?cmd=Back" as in the "Start page" command.

Thanks,

Mike

I just implemented a new flag "List after submit = 1" which does exactly this. It brings you to the summary page after the submission of a new entry. I needed the function myself. The change is SVN revision 2327 and will be contained in the next release. 

 Sorry so long getting back to you, Stefan. Just wanted to say "thank you". This new function works great!

Ok, added to the wishlist.

I had that request more than once. The problem with it is that I cannot 
implement it, since he have no LDAP server here at our institute to try it. So 
if someone teaches me how to do LDAP authorization correctly, I can put it in, 
but not before.

Hi Dimitrios,

I know where your problem is and you could actually help me in solving it. The reason of the problem is the redirection. After you login, you get redirected (via the HTTP "Location:" statement) to the start page. In an very old version of ELOG, I had relative redirection. So from https://cmsdaq.cern.ch/elog/DAQ/?cmd=Login I did a redirect to "." and voila I the browser asked for https://cmsdaq.cern.ch/elog/DAQ/. In meantime I learned that relative redirects are not allowed. Actually the Safari Browser on the MAC complains and does not support this. So my problem is not how to derive the URL for the redirection.

The standard way is the URL = ... option in the config file. So ELOG takes this URL, and adds the remainder if needed (like the entry ID after a submit, so to go to .../DAQ/123 for example). While this works fine if you only access ELOG through that URL, it breaks if you access if from different locations. Other people at BNL have the problem that they access ELOG through a ssh tunnel, so the browser URL is then http://localhost:1234 which is the local end of the tunnel. Since the redirection uses then the Apache URL, they have the same problem.

Now the big question is how to derive the URL dynamically. From your Ethereal dumps you see that there is the Referer: statement which would be one option. Actually if you install "Tamper Data", which is a Firefox extension, you can monitor the HTTP traffic much easier inside your browser than with Ethereal. The problem with this is that if you bookmark a ELOG page directly in the browser, the first access to that page does not contain any Referer: statement. The other options are the Host: or the X-Forwarded-Host: statements. The problem is that they do not contain any subdirectory, like your /DAQ/ in the example above. Furthermore, if you access ELOG through Apache and through an ssh tunnel directly for example, one URL does have the Apache subdirectory and the other has none.

So from the setup you have right now, can you derive a set of rules how to compose the forward URL from the items in the HTTP header? If you succeed, I'm happy to implement this into the next version of ELOG.

Best regards,

Stefan

But my problem begins before I log in. Trying to load https://cmsdaq.cern.ch/elog/DAQ/?cmd=Login will get me in the infinite redirection directly. Besides, I do have URL = https://cmsdaq.cern.ch/elog/ in my configuration file, so the redirection should work in my case (since I'm trying to access it through cmsdaq) and fail in every other case. Is that right or is there something I'm missing?

Cheers,
Dimitris

Hi,

The problem was coming from the fact that elog did not supports request coming from multiple hops through proxies. You got the ful string of them in the X-Forwarded-host header. Hence, you have to pick only the first one, terminated by a ','.

Here's the patch:

Thanks for the patch, I committed it to Subversion Revision #1657.

I tried to reproduce your problem, but could not. In my windows installation it looks fine. You only see the
(save and cancel) buttons only if you go to "Change [global]", otherwise you see the "Change [global]", "Delete
this logbook" etc. buttons. Have you tried with the default elogd.cfg which comes from the distribution?

Yes, I tried that. Maybe I'll have some other try on other PCs and investigate further, I'll surely let you know. Thanks
for the prompt response and compliments for your very good work! ELog is really a great piece of software.
