Hi, After googling and experimenting all morning, perhaps some kind soul would be willing to help. We have a web service that is routed through an Apache 2.2 on Windows. A correct SOAP Request would be POST http://myapache/cgi-bin/nph-owscgi.exe/olt_web/oltlogon HTTP/1.1 Accept-Encoding: gzip,deflate Content-Type: text/xml;charset=UTF-8 SOAPAction: "http://127.0.0.1:5912" <soapenv:Envelope …> … </soapenv:Envelope> Note the SOAPAction RequestHeader. This tells the “nph-owscgi.exe” where to send the request so that the application server can process the request. Some customers do not send us a SOAPHeader. In this case we would like to automatically set the SOAPHeader RequestHeader value. Here an example of a Reqeust without a SOAPHeader: POST http://myapache/cgi-bin/nph-owscgi.exe/olt_web/oltlogon HTTP/1.1 Accept-Encoding: gzip,deflate Content-Type: text/xml;charset=UTF-8 SOAPAction: "" <soapenv:Envelope …> … </soapenv:Envelope> or POST http://myapache/cgi-bin/nph-owscgi.exe/olt_web/oltlogon HTTP/1.1 Accept-Encoding: gzip,deflate Content-Type: text/xml;charset=UTF-8 <soapenv:Envelope …> … </soapenv:Envelope> Goal: to automatically set the SOAPAction if empty or missing. Here what I would expect to work, but does not. <Files "nph-owscgi.exe"> SetEnvIf SOAPAction ^h.*$ HAVE_SOAPAction RequestHeader set SOAPAction "http://127.0.0.1:5912" env=!HAVE_SOAPAction </Files> What I am trying to tell Apache is, if the SOAPAction RequestHeader starts with an “h”, then set the environment variable HAVE_SOAPAction. If the environment variable HAVE_SOAPAction is not set, then set the SOAPAction ReqeustHeader to the default value of "http://127.0.0.1:5912". Tried other Unfortunately this is not working. The SOAPAction is always being overwritten, not just if empty or missing from the request headers. Any tips what I am doing wrong? Regards Rudolf |
