All, I found the enclosed message on dejanews dated 7/5/1999. The replies to the message indicated that it is a known problem with mod_perl in Windows. Well... today, I learned that I am suffering from the same problem as this poor soul below. I am running Apache/1.3.12 with mod_perl/1.23 under Windows NT Server 4.0 SP6a. When running a time consuming process within mod_perl, the Apache server will not handle any other requests. Even /index.html will not come up until the handler is finished serving the time consuming request. I've started down the path of converting to CGI, but I wish this weren't necessary. Is this still a known problem? Regards, John Kirkland [EMAIL PROTECTED] Enclosed message: --------------------- Hi, I've noticed that a mod_perl handler blocks the Apache server while processing the request. That is, while *one* mod_perl handler is active, the server does not accept any other concurrent request! Is this a bug? Please find below the test handler. Executed as CGI script, this doesn't cause any problems -- as one would expect, the server doesn't block. Any hint is appreciated. Thanks, -- Oliver PS: Here's the script: ---> package Apache::test; use strict; use Apache; sub handler { my($r) = @_; $r->send_http_header(); $r->print("<html><body>"); $r->print("XXX"); sleep(10); ### simulating time-consuming script $r->print("</body></html>"); return Apache::OK; } <--- -----------------------
