Re: Apache::ASP and clock times
We are not sure why but it appears that the time problem may end up being specific to a DSO enabled, debian distribution of apache. When we recompiled a static version, the time that the ASP processes reported remained the same as the system clock (no changes from PDT to GMT). It looks like this is a bad-compilation problem or an effect of DSO.

From the CGI docs:
To create an empty query, initialize it from an empty string

$empty_query = new CGI("");

$empty_query = new CGI({});
This gives you a CGI object that you can use to generate your html and

Re: Apache::ASP and post-POST redirect
Uh, I found what it was!
After receiving Joshua's email, I experimented some more and while trying
to get the simplest possible configuration disabled the 'Filter' flag
(which I had turned on because I used Apache::SSI in conjunction with
ASP). And this did the trick. As soon as filtering was gone, redirects
started working again.
Hmm, I don't think I ever mentioned that ASP post-POST redirects just all
of a sudden stopped working for me. A browser would send a POST request
and never get anything back. The logs showed that the request was
processed to the point of $Response-Redirect, but nothing would ever come
out from the other side. The server was simply closing the connection
without sending any data back to the client. I did find a hack that made
redirects work by replacing ASP's Redirect with the following lines:
Apache-print("HTTP/1.0 301 Moved Permanantly\n");
Apache-print("Location: http://www.ucsd.edu\n");
Apache-print("\n");
$Response-Redirect('http://mill.ucsd.edu/index.html');
(where the last line was simply used to force apache to close the
connection) This worked as expected.
I swear this used to work before with filters on. Did something change in
Apache::Filter?

I bet its an ASP-Apache::Filter issue, because in general
there has been quite a lot with of issues coordinating
between filtered modules on the headers.
Note that in recent versions of Apache::ASP, I have started
to return the 302 status for redirects from the handler
which might be affecting this behavior.
Also the new $Server-Transfer() feature might make this
issue go away for you too, as it is an internal redirect.
Until I can look at what's causing this, you might want to
just override the *Apache::ASP::Response::Redirect sub
in your global.asa or so, so you don't have to directly
hacking Apache::ASP
sub Apache::ASP::Response::Redirect {
my($self, $location) = @_;

Apache-print("Location: $location\n");

More on the set_handlers() / push_handlers() bug...
Hello, again. Here's a quick summary of the problem: upon clearing the stack of handlers (with set_handlers(PerlAuthzHandlers = undef)) the server appears to not recognize when it has found a DirectoryIndex file and returns the contents of a directory instead of the index file. Since last writing on this topic, I upgraded to all of the newest versions (apache-1.3.12, perl-5.6, mod_perl-1.24) and configured mod_perl with PERL_TRACE=1. Looking at the error_log with the handler tracing on and httpd running in single-server mode, I discovered that the server does appear to cycle through the directory indexes, but doesn't realize when it has found one. I've attached two error logs for the request http://dw3.tivoli.com:81/home/passwd/group/: one with the cache enabled, one without. I've also attached a copy of the document returned by the server for the with-authz-cache request. The document is the auto-generated contents of the directory. As you can see, index.phtml does exist in the directory and is the first file searched for by the server. Does anyone have any ideas here? Can anyone reproduce the problem? I've also included the source for the AuthzCache and AuthzLDAP. If anyone could use at least the Cache code and see if you could reproduce the problem, I'd really appreciate it. I noticed that the error log with the cache enabled shows that subsequent internal requests (such as those you see when requesting a directory instead of a named file) don't reset the handler stack to what is in the configuration. See about line 65 of each log file for this difference. Regards, Christian - Christian Gilmore Infrastructure Tools Team Lead Web Multimedia Development Tivoli Systems, Inc.

So if i didn't want to wait, how would I go about getting an RSA liscense? to have a mod_ssl server before then. Also, are the CA's willing to sign for this time of server?

When I checked into this Raven SSL seemed to be the solution. It is basically mod_ssl with an RSA license. Some people also suggested that if you buy the Red-Hat server package (or whatever it is called) which includes a RSA license, you could just put it into a corner and use mod_ssl. But I am not sure if that kind of 'license transfer' is really legal. Gerd

Re: Apache/mod_perl
The problem is cost. If licensing were cheap, Stronghold, Raven, and others would have a somewhat hard time staying in business (an issue they'll all have to address soon enough). The SSL vendors have an OEM license of some sort and so what you pay for a right-to-use license is a much smaller hunk of change especially because it's spread across a large customer base. So, if you can't wait till September, don't want to risk being in violation of a license and getting caught, and don't want to fork over $3-4K, the Stronghold/Raven route is a much better choice. -- Rob --On Friday, July 07, 2000 12:42 PM -0700 Scott Alexander [EMAIL PROTECTED] wrote: So if i didn't want to wait, how would I go about getting an RSA liscense? to have a mod_ssl server before then.

RE: More on the set_handlers() / push_handlers() bug...
Forgive me for the obvious and probably stupid questions, (especially since I didn't see the earlier posts in which you probably answered them =o) but just for the record -- No problem. I appreciate your trying to help! Could you be misspelling "PerlAuthzHandler"? I note you said "PerlAuthzHandlers" with an 's' below Is that a feature I should kick myself for not being aware of? Or maybe just an email typo? Or a code error? (I do see it's a stack of handlerS, but) Heh. No, that was just a typo in my mail. I have it right in the handler code, which I had attached. Why undefine the handlers? Could you just use $r-set_handlers( PerlAuthzHandler = [ \OK ] ); or something? Could that be part of the problem? (Though I don't see how.I'm still pretty new to this.) Well, setting it to undef is what is recommended in the "Apache Modules" book (page 466), but I have tried setting it to \OK. Setting it to \OK turns out to do nothing at all. The server ignores your attempted change (even though it shows that it did change when you look at get_handlers) and continues as if you never even called set_handlers. Please, if you have the time and opportunity, give the AuthzCache a try. I'd really like to know that others can reproduce the problem. It can wrap around any perl Authz handler as follows: PerlAuthzHandler Tivoli::Apache::AuthzCache your authz handler here Tivoli::Apache::AuthzCache::manage_cache Regards, Christian - Christian Gilmore Infrastructure Tools Team Lead Web Multimedia Development Tivoli Systems, Inc.
Re: Apache/mod_perl
The issue has less to do with the cost of the whole thing, then with Strong hold having horrible support as well as a laundry list of other problems. Our as we convert our code base into completely mod_perl modules, the stronghold 2.4.2 has to be replaced by either 3.x or going to some other solutions based on apache/mod_perl/ssl component. Stronghold on solaris won't run the perlhandler that we want it to. The question were facing is whether it is worth it to go after the 3.x upgrade for strong hold or some other route. I'm going to try the raven 30day trial and see if i can make that work the way we want it to. Scott On 7 Jul 2000, at 16:42, Vivek Khera wrote: You don't get a license from RSA cheaply.

Re: Apache::ASP and post-POST redirect
Dmitry Beransky wrote:
Hmm, I don't think I ever mentioned that ASP post-POST redirects just all
of a sudden stopped working for me. A browser would send a POST request
and never get anything back. The logs showed that the request was
processed to the point of $Response-Redirect, but nothing would ever come
out from the other side. The server was simply closing the connection
without sending any data back to the client. I did find a hack that made
redirects work by replacing ASP's Redirect with the following lines:
I don't know a thing about Apache::Redirect, but I've had this same
problem before: a handler returning REDIRECT after reading POST data
would freeze the apache process (it got stuck trying to read the data
again).
The work-around I used is to set $r-header_in("Content-length", 0) just
after reading the POST data. Then, if some cleanup function in apache
tries to read it again, it finds that there is none to read.
