I've been trying to get Windows Sharepoint Services running with a trial version of APE for the last couple of days, and after the usual hurdles of WSS zones, etc, I was able to get to the normal FBA login screen as usual.

If I'm internal accessing the inside DNS name, I can successfully login. If I go via the reverse proxy going through APE it fails. I get a 502 Bad Gateway error after I submit the form for login.

Running a packet sniffer on the reverse proxy box, and HTTPFox on the local client, I can see the request to the back end work successfully, and it returns this... (I've trimmed the non-essential bits out)

So I gather the issue is something in APE or IIS on that box. I checked the IIS logs, and they are empty. So I checked my rewrite logs, and this is how it looked (again - sanitised)

10.***.***.*** 10.***.***.***  [15/Jun/2009:18:06:16] [internal.domain.com/sid#1589845953][rid#7837633/initial] (1) [perdir c:\program files\helicon\ape\] init rewrite engine with /_layouts/login.aspx

10.***.***.*** 10.***.***.***  [15/Jun/2009:18:06:16] [internal.domain.com/sid#1589845953][rid#7837633/initial] (1) [perdir c:\program files\helicon\ape\] go-ahead with proxy request http://internal.domain.com:8008/_layouts/login.aspx?ReturnUrl=%2fdefault.aspx [OK]

So the request is going to the back end server happily.

But looking at what HTTPFox is seeing leaving and returning is not the same. It goes out like this...

POST /_layouts/login.aspx?ReturnUrl=%2fdefault.aspx HTTP/1.1

but the location from the responding server (which isn't the back end one)

Location /_layouts/login.aspx.apehandler?ReturnUrl=%2fdefault.aspx

Is this apehandler supposed to be in there?

This is the config from the httpd.conf

<VirtualHost ***.***.***.***:443>
#
# The following code enables most detailed logging for mod_rewrite
#
  RewriteLog  E:\SHAREPOINT_REVPROXY\rewrite.txt
  RewriteLogLevel 9

  SetEnv proxy-nokeepalive 1
  SetEnv force-proxy-request-1.0 1

  <Proxy *>
    Order Allow,Deny
    Allow from all
  </Proxy>

  ProxyRequests off

  RewriteEngine On
 
#
# If looking for no page, redirect to default.aspx for the Sharepoint site
#
  RewriteCond %{HTTP_HOST}  ^internal\.domain\.com$   [NC]
  RewriteCond %{REQUEST_URI} /       [NC] 
  RewriteRule ^/$   /default.aspx      [NC,R]

#
# If any request for the Sharepoint site, map to the internal box
#
  RewriteCond %{HTTP_HOST}  ^internal\.domain\.com$   [NC]
  RewriteRule ^(.*)$    http://internal.domain.com:8008$1 [NC,QSA,P]

  ProxyPassReverse  /          http://internal.domain.com:8008/

  <Location />
    ProxyPassReverse http://internal.domain.com:8008/
    ProxyPassReverse internal.domain.com:8008
  </Location>
</VirtualHost>

Has anyone had any luck getting this to work? Or am I blindly missing something obvious?

I missed one little part - turning the error log also on. After I did, I found this...

[15/06/2009 7:14:17 PM] proxy Done with error: HttpWebRequest.BeginGetResponse (http://internal.domain.com:8008/_layouts/login.aspx?ReturnUrl=%2fdefault.aspx), error: System.ArgumentOutOfRangeException: Index and length must refer to a location within the string.

   at System.Net.ContextAwareResult.FinishPostingAsyncOp()
   at System.Net.HttpWebRequest.BeginGetResponse(AsyncCallback callback, Object state)

That would have helped in the first post...

Hello,
Thanks for detailed information regarding the issue. However we need one more thing to investigate it. Would you please either provide WFetch logs for requests to the back-end, or allow us to get them through temporal access to the back-end.

Hmmm.. Couldn't get WFetch to work properly. WSS is being cagey, or I have no idea what I'm doing. I'm going with the latter.

I used HTTPFox to pull out some details - maybe these will help.

So I'm not sure what it could be... The only thing I am suspecting at this point (but it could also very wrong) is that the cookie could be breaking stuff... (the httponly. It doesn't match key=value syntax) Everything else looks normal - standard 302 redirects, and nothing in the the content that would throw a bad response.

 Hello!

Location header must contain full URL including protocol, host and path. SharePoint server returns wrong Location header only with url path.
We have found a bug in processing of such wrong Location headers in mod_proxy. This bug will be fixed in the next build.

Your proxy-reverse rules must be as follows:

ProxyPassReverse / http://internal.domain.com:8008/
# optional rule for you configuration for wrong Location processing
ProxyPassReverse / /

Section <Location /> is redundant.

Thanks for help! We may offer you a discount coupon for Helicon Ape.

I started without the <location> entries. That's just where I was up to when I posted here.

Changing to what you have suggested made no difference, so I guess I have to wait for the next build. (Is there a rough ETA, so I can let management know?)

And happy to help - its nice to see a decent project bring some of Apache's functionality across. I have another box using Apache using mod_rewrite, mod_proxy and mod_proxy_html for another application with 14 back end servers around the world. Compiling those libraries, etc was a head-ache, so this seemed the obvious choice to simplify things a bit.

I've worked a way to get passed the issue (not practical, but it works), but have come across other issues with Sharepoint - it has URLs in the javascript in some places, sometimes in <OPTION> tags, and to make it even more complicated, it has unicode slashes in other URLs... Microsoft. Got to love them.

We plan to release the build at next week.

Directive 'ProxyPassReverse / /' is not optional, it will correct wrong Location header.
