Bruce: thanks for the info. With a command line client, I can get your response, but the headers it returns throw some clients off (like FF for e.g.).
Here's the headers I get back from your server and a working pycsw install:
$ GET -e -d "http://localhost/pycsw/trunk/csw.py?service=CSW&version=2.0.2&request=GetCapabilities"
Connection: close

Can you make sure your IIS supports chunked transfer encoding perhaps? http://support.microsoft.com/kb/278998
Thanks for the valuable testing and feedback again.

> > I added system added environment variable for 'HTTP_HOST' and 'REQUEST_URI'. That appears to have gotten me further along. But, I have another hurdle to clear it appears. See below. I've got simple test python scripts working in the same web directory as cws.py. They can be seen here:http://dev.insideidaho.org/pycsw/test.py and http://dev.insideidaho.org/pycsw/test2.py. So, I think (fingers crossed) that I have the web server configured correctly but maybe I am overlooking something. When I use the pycsw tester to try make a GetCapabilities request I get a 502 error. Pycsw tester is here: http://dev.insideidaho.org/pycsw/tester/index.html When I run pycsw on the localhost machine I get this response with more details: #############################BEGIN RESPONSE################################# <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>IIS 7.0 Detailed Error - 502.2 - Bad Gateway</title> <style type="text/css"> <!-- body{margin:0;font-size:.7em;font-family:Verdana,Arial,Helvetica,sans-serif;background:#CBE1EF;} code{margin:0;color:#006600;font-size:1.1em;font-weight:bold;} .config_source code{font-size:.8em;color:#000000;} pre{margin:0;font-size:1.4em;word-wrap:break-word;} ul,ol{margin:10px 0 10px 40px;} ul.first,ol.first{margin-top:5px;} fieldset{padding:0 15px 10px 15px;} .summary-container fieldset{padding-bottom:5px;margin-top:4px;} legend.no-expand-all{padding:2px 15px 4px 10px;margin:0 0 0 -12px;} legend{color:#333333;padding:4px 15px 4px 10px;margin:4px 0 8px -12px;_margin-top:0px; border-top:1px solid #EDEDED;border-left:1px solid #EDEDED;border-right:1px solid #969696; border-bottom:1px solid #969696;background:#E7ECF0;font-weight:bold;font-size:1em;} a:link,a:visited{color:#007EFF;font-weight:bold;} a:hover{text-decoration:none;} h1{font-size:2.4em;margin:0;color:#FFF;} h2{font-size:1.7em;margin:0;color:#CC0000;} h3{font-size:1.4em;margin:10px 0 0 0;color:#CC0000;} h4{font-size:1.2em;margin:10px 0 5px 0; }#header{width:96%;margin:0 0 0 0;padding:6px 2% 6px 2%;font-family:"trebuchet MS",Verdana,sans-serif; color:#FFF;background-color:#5C87B2; }#content{margin:0 0 0 2%;position:relative;} .summary-container,.content-container{background:#FFF;width:96%;margin-top:8px;padding:10px;position:relative;} .config_source{background:#fff5c4;} .content-container p{margin:0 0 10px 0; }#details-left{width:35%;float:left;margin-right:2%; }#details-right{width:63%;float:left; }#server_version{width:96%;_height:1px;min-height:1px;margin:0 0 5px 0;padding:11px 2% 8px 2%;color:#FFFFFF; background-color:#5A7FA5;border-bottom:1px solid #C1CFDD;border-top:1px solid #4A6C8E;font-weight:normal; font-size:1em;color:#FFF;text-align:right; }#server_version p{margin:5px 0;} table{margin:4px 0 4px 0;width:100%;border:none;} td,th{vertical-align:top;padding:3px 0;text-align:left;font-weight:bold;border:none;} th{width:30%;text-align:right;padding-right:2%;font-weight:normal;} thead th{background-color:#ebebeb;width:25%; }#details-right th{width:20%;} table tr.alt td,table tr.alt th{background-color:#ebebeb;} .highlight-code{color:#CC0000;font-weight:bold;font-style:italic;} .clear{clear:both;} .preferred{padding:0 5px 2px 5px;font-weight:normal;background:#006633;color:#FFF;font-size:.8em;} --> </style> </head> <body> <div id="header"><h1>Server Error in Application "DEFAULT WEB SITE/PYCSW"</h1></div> <div id="server_version">Internet Information Services 7.0<BR></div> <div id="content"> <div class="content-container"> <fieldset><legend>Error Summary</legend> <h2>HTTP Error 502.2 - Bad Gateway</h2> <h3>The specified CGI application misbehaved by not returning a complete set of HTTP headers.
