Hello everybody,

I have a problem with an SRS implementation on a Linux box and
would like to have the advice of this precious list.

The problem relates to a peculiar implementation of SRS that uses
an ad hoc interface to query the databanks. Essentially, the interface
behaves as follows:

- databanks to be queried and terms to be searched are posted by 
  using a standard HTML form. The same form is used by end users
  to specify if a preliminar search within a set of dbs of synonyms
  is to be carried out

- the action that is associated to the form launch a perl script
  that: i) checks if a search through synonyms is requested,
  ii) possibly call getz for carrying out the synonyms search,
  iii) combine the results of the preliminar search with the 
  original search terms, iv) call wgetz with the combined data 
  and v) return the output of wgetz to the end user.

The script is currently working ok with perl 5.005 + perl modules
HTTP.pm and URI.pm on a Solaris box, an IBM RISC machine running AIX 
and a Dec Alpha workstation.

We are having a (maybe silly) problem on a Linux machine: here are
the symptoms.

When a search is performed by using the standard SRS interface,
everything is ok.

When a search is carried out through the above perl script, it 
displays the right results, but it is not possible to reach the 
single entries by clicking on their ids because the temporary
directory is empty. In other words, the user.par file that is 
normally created in the user session directory is missing...

I understand that the user.par file is created by wgetz. So, 
my final question to you all is the following: 

in which conditions, on a Linux box, it can happen (or happened) 
that the user.par file is not created?

I know there are many possible causes that do not relate to SRS.
E.g., wrong perl modules that are badly managing passing of parameters
to wgetz. But if you have any ideas, you are welcome to tell me!

And of course you are welcome to see it all in action at the
following url:

Thank you in advance for any hints and suggestions.

Ciao. Paolo Romano
