As for the original problem you're trying to solve, if you turn ProxyPreserveHost Off and you add hostname.example.com (the DNS name of the reverse proxy host itself) with IP 10.11.12.13 (the IP of the Exchange server) to your /etc/hosts on the reverse proxy, you won't need to bother with mod_proxy_html for Outlook Web Access. You can then do ProxyPass and ProxyPassReverse statements with the reverse proxy's hostname instead.

What makes it somewhat sophisticated is that the reverseproxy itself is located behind a firewall and has only a local IP address. So it has to rewrite every (internal) hostname or IP address in html documents to the external hostname that is seen from the outside. With mod_proxy_html this works for all the occurances in normal html source but the modul refuses to rewrite internal addresses into CSS descriptions. (I managed to have the hostname rewritten whenever it occurs in Javascript parts of the documents) If I look into the source of the delivered document it still shows the internal URL in between CSS statements. My Configuration is as follows: ProxyPass / http://10.11.12.13/ ProxyPassReverse / http://10.11.12.13/ SetOutputFilter proxy-html ProxyHTMLExtended On ProxyHTMLURLMap 'http://10.11.12.13' 'https://hostname.example.com' The host 10.11.12.13 is the Windows Server delivering the OWA documents, 'https://hostname.example.com' is the hostname for access from the outside. Most likely my filter definition is not entirely correct, but the several documentations on the mod_proxy_html website don't help me much. Are my config directives ok? Am I missing something? For instance, one of the culprits looks this way: ---------------------------- <div id="idMsgViewer" class="msgViewer" accesslevel="63" acceptlang="de" rowsperpage="25" url="http://10.11.12.13/exchange/dirk/Inbox/"; onready="onViewReady()" onrefresh="onViewRefresh()" onbeforerefresh="onBeforeViewRefresh()" onkeydown="onViewKeyDown()" onkeypress="onViewKeyPress()" oncontextmenu="return(false);" refreshthreshold="20%" viewdescriptor="xmlDefaultView" onchangesort="persistSortOrder()" onerror="onViewError()" onnavigate="onViewNavigation()" onselectionchange="updatePreviewPane()" allowquickflag="1" followuptext="Nachverfolgung" loadingtext="Wird geladen" nextseldir="1"> ---------------------------- I asked this question in alt.apache.configuration some weeks ago, received some help, but the problem still exists.
