Hi all,
Apache HTTPD 2.4.34 on Windows 10 downloaded from Apache Haus.
I'm trying to move a corporate application behind a reverse proxy. In
the process, I need to move the path this application is published on, eg:
/webapp1 --> /suite/webapp1
"webapp1" contains a specific JSP that returns an HTML page with a lot
of JavaScript inside, which hardcodes an absolute path "/service1". I
need to move that one as well to under the external "/suite/service1" path.
The GET /webapp1/the.jsp request has the following headers:
GET /webapp1/the.jsp HTTP/1.1
Accept: image/gif, image/jpeg, image/pjpeg,
application/x-ms-application, application/xaml+xml,
application/x-ms-xbap, */*
Referer: <redacted>
Accept-Language: en-US
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 10.0;
WOW64; Trident/7.0; Touch; .NET4.0C; .NET4.0E; Tablet PC 2.0)
Accept-Encoding: gzip, deflate
Host: <redacted>
Connection: Keep-Alive
Cookie: JSESSIONID=24B3D3B40235B8E889A5F019081AAB41
The response (non-proxied) has the following headers
HTTP/1.1 200
Strict-Transport-Security: max-age=31536000;includeSubDomains
X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Content-Type: text/html;charset=ISO-8859-1
Transfer-Encoding: chunked
Content-Encoding: gzip
Vary: Accept-Encoding
Date: Tue, 04 Sep 2018 06:52:12 GMT
Server: <redacted>
I've set up the following in httpd.conf:
FilterDeclare INFLATE_HTML CONTENT_SET
FilterProvider INFLATE_HTML INFLATE "%{CONTENT_TYPE} =~ m|^text/html|"
FilterProtocol INFLATE_HTML change=yes
FilterTrace INFLATE_HTML 1
FilterDeclare DEFLATE_HTML
FilterProvider DEFLATE_HTML DEFLATE "%{CONTENT_TYPE} =~ m|^text/html|"
FilterProtocol DEFLATE_HTML change=yes
FilterTrace DEFLATE_HTML 1
FilterDeclare SUBST_HTML
FilterProvider SUBST_HTML SUBSTITUTE "%{CONTENT_TYPE} =~ m|^text/html|"
FilterTrace SUBST_HTML 1
<Location "/suite/webapp1/the.jsp">
FilterChain +INFLATE_HTML +SUBST_HTML +DEFLATE_HTML
ProxyPass ${internal}/webapp1/the.jsp
ProxyPassReverse ${internal}/webapp1/the.jsp
Substitute s|/service1|/suite/service1|n
</Location>
This doesn't work. I can see the request being forwarded to the internal
application server, which executes successfully and responds with 200,
but something inside HTTPD doesn't work, and it ends up at the browser
with a 504 and no data (looking at this with Fiddler).
The HTTPD error.log file contains:

(this might contain a few lines related to other requests as well).
I tried as well with "AddOutputFilterByType INFLATE:SUBSTITUTE:DEFLATE
text.html", doesn't work either.
Does anybody have any idea what I'm doing wrong?
Regards, Maarten
