Subject Re: [users@httpd] Intermittent CGI data
Date Tue, 19 Oct 2004 19:28:40 GMT

Ok, sorry, it's a weird one... Method can be post or get. Script 1 
generates the form or the get request and passes information on to script 
2. Script 2 sometimes receives the information and works properly, other 
times it does not get the data from script 1. It seems to be a server 
problem because it happens with more than one set of scripts on this server 
and each is different, and if I move these scripts to another server they 
work fine. The scripts are written in perl and the cgi data is retrieved 
via environment variables $ENV just like it's done a hundred times on other 
servers here, but this machine has trouble intermittently and the data 
doesn't always make it to the second script. If it didn't work at all it 
would be much easier to fix, but it just seems to not-work occasionally. 
I've installed some code to check the incoming cgi data in script 2 and 
sometimes it's just not there. Worse yet, the customer will try it while 
I'm on the phone with them and their page will come back empty, I'll do the 
exact same thing and mine will work fine. And then sometimes it will give 
me an empty page too. Data passed to script 1 from another server always 
seems to work, but data from a script on this server passed to another 
script on this same server is intermittent. The scripts are not complicated 
at all, just a little data processing and send a web page back....

I'm yankin' out what little hair I have left..... It could be perl I guess, 
or BSD, but I thought I'd start with the apache server to see if anyone had 
any ideas....
