The UDP connection you mention is only used locally for inter-process communication. When I implemented that, I
made extensive tests and found that there is never a packet being dropped. This happens for UDP only if the packet
goes over a physical network. Maybe this is different in modern Linux versions, so one should double check this

 04 Dec 2009, Stefan Ritt, Info, Custom page showing ROOT analyzer output 
|
Many midas experiments work with ROOT based analyzers today. One problem there is that the graphical output of the root analyzer can only be seen through
the X server and not through the web. At the MEG experiment, we solved this problem in an elegant way: The ROOT analyzer runs in the background, using
a "virtual" X server called Xvfb. It plots its output (several panels) normally using this X server, then saves this panels every ten seconds into GIF |

23 Sep 2013, Stefan Ritt, Info, Custom page header implemented
|
Due to popular request, I implemented a custom header for mhttpd. This allows to inject some HTML code
to be shown on top of the menu bar on all mhttpd pages. One possible application is to bring back the old
status line with the name of the current experiment, the actual time and the refresh interval.

As reported in the bug tracker, the proposed header does not work if no specific (= different from the default 60 sec.) update period is specified,
since then no cookie is present. Here is the updated code which works for all cases:

I am not sure what to do with the javascript snippet - I understand it should be somehow connected to /Custom/Header, but if I create the /Custom/Header
string, I cannot put this snippet
into this string using odbedit - if I try to cut&paste it into odbedit, it is truncated to the first line - nor using the mhttpd odb editor - when I cut&paste |

Just read elog:908, it tells you to put this into a file, name it header.html for example, and put into the ODB:
