mod_perl/Apache troubles with cell phone
I've been pulling my hair out this evening trying to resolve a problem serving content to a cell phone.
Phone is a LG VX-4500. I've written a simple handler as a start to just send "Hello" to the phone along with a Content-Length and Connection: Close header but the phone just times out. With a browser, all is well. File-based (non mod_perl) content gets to the phone fine, it's only the mod_perl content that is timing out. I can see the requests coming and going in the logs. It looks like the data just never gets sent back to the phone.
Running:
Debian Sarge
Apache 2.0.52
mod_perl2
Any thoughts on this would be appreciated.

Rodger, you will need to send me one of those toys if you want me to test
it for you :)
Seriously, you provide too little information to work with. Does your
modperl setup work with a normal browser? What do you see in error_log and
access_log files on those requests? Finally saying, I run mod_perl2, is
not a way to report a problem, please take a look at:

Perrin,
My first inclination upon reading this post was "Silly, of course I checked the headers."
However, upon doing what you suggested by putting the CGI.pm script and mod_perl version side by side in lynx, the only difference was the following header:
Cache-Control: max-age=0 must-revalidate
I took that out and it works fine. Further inspection reveals that Cache-Control is apparently an HTTP1.1 feature. I replaced it with the HTTP1.0 'Pragma: no-cache' and that worked out fine.
Thank you so much for the suggestion. I'm sure it was suggested before, but perhaps I just needed to time away from it to look deeper.

This almost certainly means that your mod_perl script is not sending out
the right headers. Look at the complete response headers using GET or
lynx or something and compare them to see what's missing in your
mod_perl script.

Thanks to all for all the suggestions. I've been afk for a couple days.
This particular phone uses a 'standard' html browser, i.e. the content doesn't have to be wml. We've worked with a few of these before now.
I got around the immediate problem by a per-file <Location> directive for the particular script in question and writing it with CGI.pm with no problems.
In response to some other suggestions on this thread, the access log shows the same entry for the cell phone as it does with a normal browser (IE, Opera and Firefox) with the exception of User Agent. There are no entries in the error log for these requests.
I'll be reviewing the suggestions made and posting my results to this thread as soon as I get settled back in from my trip. 8 hours in a van with 2 toddlers is a bit distracting.
Again, thanks for all the help.
