Caching with $r-no_cache(1)
I notice that the Guide omits the mention of Netscape's ignorance of Expires: set to the same as Date: when it mentions $r-no_cache(1) performing that function. Currently, I'm experiencing the problem with Netscape 4.7, although I seem to recall the same problem in earlier releases, in the case where the target browser's clock is slow. Of course, the server-side workaround (since we can't just fix our visitor's clocks) is to set an Expires header that significantly in the past, for some definition of 'significant'. I'm going to assume that $r-no_cache(1) won't be kludged to fix Netscape's bug, although some would argue that it should be 'fixed' in mod_perl. As an update to /guide/correct_headers.html#2_1_3_Expires_and_Cache_Control, I'd suggest adding the following text at the end: [ ... works with the major browsers. ] However, Netscape clients with slow clocks may not honor the 'immediate' timeout, cacheing pages anyway. This can be corrected by explicitly setting an Expires header that's in the past. How far in the past depends on how lenient you wish to be with browsers with slow clocks. Something between 5 and 30 minutes seems reasonable to me, but discussion may demonstrate a different approach and/or timeframe. Thoughts? Randy

Well, quite a lot of computers now fire up with the clock saying some time around 4 Jan 1980. Just how far do you let this go? My view is that if he suspects that it may cause a problem, one should tell his user to make sure the clock is right. Caveat browsor. I feel sure that deliberately lying about the time is a dangerous path to tread. Of course we can't (yet) expect everyone to be running ntpd, and five minutes doesn't initially seem unreasonable, but we could then expect biennial fun and games when daylight savings time kicks in and out, or not, as the case often may be. The software industry has a bad enough reputation as it is, without yet another kind of periodic Y2k bug. Maybe a Request For Comment? Or a word in someone's ear at the browser development labs? 73 Ged.
Re: Looking for Maurice Aubrey maurice@hevanet.com
Before taking the drastic step of grabbing a hold of the IPC::ShareLite namespace (I prefer this to a branch split), how long have you been trying to contact him? Where I live, I know a few people that took off big time during the Millenium holiday. I don't think it is unusual that someone might have taken a month off to party and vacation around this time.

send_fd and timeout problem
Hi, I'm using send_fd() to send relatively large files. Apache's Timeout is currently set to 60s and indeed, mod_perl aborts as soon as the minute elapses. (error msg: mod_perl: Apache-print timed out). However, it shouldn't do that, right? As ap_send_fd_length() does 8k chunking and uses a soft timeout, reset for each chunk, I would have expected that it would only abort if it couldn't send 8k within a minute. This would also match Apache's Timeout documentation saying "The amount of time between ACKs on transmissions of TCP packets in responses". Any suggestions? Thanks, Martin

mod_rewrite and -U Problems
I have a question about the -U test under mod_rewrite. The docs state that the test "Checks if TestString is a valid URL and accessible...". Well, the problem I am having is that if I give it a path the clearly does not exist on my system, the logs report that it does the check and returns a 200(OK). For instance, if I have a a URL that I send it: http://test.mydomain.com/click?url=hjk And then if I extract and do a -U test on 'hjk', it will report a 200 OK and try to redirect (I have indicated in my scripts to redirect only if the URL is valid, which is what I thought -U would accomplish). I have the log verbosity on 9, so I am certain that it is using _only_ the 'hjk', and not extra stuff. Specifically, the flow from the logs is: xxx.xxx.xxx.xxx - - [07/Jan/2000:16:59:13 -0500] [xxx.xxx.com/sid#8100034][rid#81a8034/initial] (5) RewriteCond URI (-U) check: path=hjk - status=200 xxx.xxx.xxx.xxx - - [07/Jan/2000:16:59:13 -0500] [xxx.xxx.com/sid#8100034][rid#81a8034/initial] (4) RewriteCond: input='hjk' pattern='-U' = matched xxx.xxx.xxx.xxx - - [07/Jan/2000:16:59:13 -0500] [xxx.xxx.com/sid#8100034][rid#81a8034/initial] (2) local path result: jh Does anyone know the inner workings of this module who could give me some insight as to why this happens? Is there another way that I can verify the validity of a URL, external or internal, from within mod_rewrite (or anything else I can use from within a configuration file)? Thanks!

Re: Weird message from make test
Thanks for all the pointers. Do you know where I can find the CGI.pm changes file? Here's my question, why do I really need to figure this out in the first place? Shouldn't modperl (at least its test scripts) work w/ any version of CGI.pm? Could I assume that the test script is wrong somehow? If it's not the test script that's bad, then it would have to be CGI.pm, no?
