Seite drucken - Reverse Proxy will nicht mehr

Langsam aber sicher drehe ich durch. Ich komme einfach nicht dahinter, was da schief läuft. Daher brauche ich bitte ein bisschen Hilfe, von Leute, die sich mit einem reverse Proxy unter Apache auskennen.

Folgendes Szenario: Es gibt n Domino Server für n Tochterfirmen

Aus dem Internet ist ein Reverse Proxy über eine öffentliche IP Adresse erreichbar

Die Anfragen (inotes) an den Proxy werden dann wie folgt weitergeleitet:

* http://xxx.xxx.xxx.xxx/ --> http://serverA
* http://xxx.xxx.xxx.xxx/company1 --> http://serverB

+-------+
|ServerA|
+-------+
/
+----------+ +---------------+
| Internet +----+ Reverse Proxy|
+----------+ +---------------+
\
+-------+
|ServerB|
+-------+

Die Anfrage an Server A unter
http://xxx.xxx.xxx.xxx/mail/ukrause.nsf funktioniert einwandfrei

Die Anfrage an Server A unter
http://xxx.xxx.xxx.xxx/COMPANY1/mail/ukrause.nsf funktioniert nur insoweit, dass die ERSTE Anfrage an den Server B erfolgt, dann aber versucht wird, die restlichen Daten von Server A zu holen, wo die Datei natürlich nicht liegt.

Man sieht im Browser, daß sich die URL ändert von http://IP/COMPANY1/mail ... in http/IP/mail/...

Ich kann von INTERN problemlos auf die Datenbank auf Server B zugreifen; auch funktioniert es, wenn ich die Proxykonfiguration so umschreibe, dass Server B auf / hört.

Ich habe heute den Proxy komplett neu aufgesetzt und eine Konfiguration eingespielt, die vor einem Jahr noch einwandfrei funktioniert hat.

Der Pfad von extern nach intern sieht so aus; habe ich auch schon alles überprüft, da geht nichts irgenwie dran vorbei.

+---------+ +--------+ +------------------+ +------------------+
|Internet| -- |Firewall| -- | Reverse Proxy| -- |DominoServer |
+---------+ +--------+ +------------------+ +------------------+

Ich weiss echt nicht mehr weiter und brauche dringend Unterstützung.

Hi Ulrich,

kannst du mir mal die Config mailen? Ich schau sie mir gern an.

Leitest du von dem Reverse Proxy zu einer Redirect-DB? Was ist da eingestellt? Hier könnte auch das Problem liegen, weil die Redirect-DB im Personendokument nachsieht und den Pfad übernimmt.

Grüsse
Christoph

Ist beim Apache ev. noch ein mod_rewrite oder ähnliches installiert, was Dir in die Konfig pfuschen könnte?

nein, mod_rewrite ist nicht vorhanden

Das Problem liegt ganz woanders (siehe mein Reverse Proxy Thread mit Konfiguration).

Wenn du Server1/Comp2/test anfragst, weiß der Server dahinter ja nicht, dass der Pfad umgelegt wurde. Dementsprechend liefert er Seiten mit den Links zu Server1/test2 aus, ohne das Comp2.

Diese Umsetzung muss man im Apache dann machen, dass hier auch der Ordner auftaucht. Entweder mit mod_html (oder mod_http? eines von beiden) (wandelt alles in XML und parst gut, aber zerstört oft die Gestaltung - unbrauchbar) oder z.B. mit mod_sed. Das ist aber eine ziemliche Fleißarbeit, bis iNotes damit sauber läuft.

Mit mod_proxy kommt man bei der Konstruktion mit Unterordnern nicht aus. Nur über verschiedene VHosts ginge das.

LG

Komisch nur, dass es bisher immer problemlos funktioniert hat.

Ich hab mal paar Seiten im Web dazu gelesen und befürchte du brauchst den mod_rewrite oder du mußt die Links im iNotes anpassen.

v.a. der Post http://atnotes.de/index.php?topic=44147.0 (http://atnotes.de/index.php?topic=44147.0) macht mich da stutzig. Der Artikel http://www.ibm.com/developerworks/web/library/wa-secdomdat/ (http://www.ibm.com/developerworks/web/library/wa-secdomdat/) liest sich auch interessant, wobei der mehr auf die Security geht.

Ich hoffe ich kann das die nächsten Tage nachstellen, mit ReverseProxy bastle ich gern rum. :-)

Grüsse
Christoph

Hi,

in dem Text bei IBM geht es auch wieder um eine VirtualHost basierte Lösung, nicht um Verzeichnisse. Ist sicher der Weg des geringsten Widerstandes, kostet halt nur mehr bei den SSL Zertifikaten. (Stichwort iPhone Veranstaltung @eknori).

Hat jenand die mod xml2_enc.so oder so fuer mich?

mod_xml2enc (http://apache.webthing.com/mod_xml2enc/)
Einfach über die Paketverwaltung Deines OS installieren?

Dachte ich auch, finde es aber beim sles nixht

Schräg. Muss man anscheinend selbst kompilieren.

Da kann ich machen, was ich will . Kriegs einfach nicht kompiliert. Habe mich strikt an die Anleitung gehalten; nada ...

Frage: WAS mit Edge Components. Ist das damit möglich? Hat das schon mal jemand umgesetzt ?

Edge haben wir hier am Laufen, ich würde beim Apache bleiben.

Welche Fehlermeldung/en bekommst du?

Hier die Ausgabe. Aber was soll es, wenn es verzeichnis basiert sowieso nicht funktioniert?. Langsam habe ich keinen Bock mehr auf die ganze Schei..

Für das Protokoll: Mit zwei 8.0.2 Domino Servern funktioniert meine ursprüngliche Konfiguration. Nach einem Update auf 8.5 nicht mehr ...

Egal, ich habe jetzt auf virtuelle Server umgestellt. Wird zwar ein paar ServiceCalls geben, weil nun die URI au den _default_ server nicht mehr funktioniert und dies auch mit mod_rewrite nicht in den Griff zu bekommen ist.
