  • Reverse Proxy FastCGI error

    Aug 20, 2009 06:06 PM|Vince3868|LINK

    Problem Background:

    I am currently trying to overcome an IIS/Apache DOM communication issue in which the PHP application opens a window which is dynamically trying to communicate to the parent/opener DOM (i.e. the IIS webserver). This results in a cross-domain 'access denied' error.  I understand that setting up a reverse proxy via ARR/Url Rewrite will resolve this issue.

    In my development environment (Dual IIS7/XAMPP webserver) I have therefore:
    - created the empty web folder (c:\inetpub\wwwroot\srvr2\ucourse)
    - installed Application Request Routing Module,
    - enabled the proxy,
    - set the Match URL details to:
     - Matches the pattern
     - Using wildcards
     - Pattern: <IIS_HOSTNAME>/ucourse/*
    - set no conditions
    - set the Action details to:
     - rewrite
     - Action Properties: http://<APACHE_HOSTNAME>:8080/{R:1}

    Result:
    Various URL tests show me that the filtering pattern matching is working (i.e. all browser URL calls to the IIS server still go through correctly except for ones with '/ucourse' appended to the hostname). The problem I'm running into is that the rewrite consistently returns the following:

    Error Summary: HTTP Error 500.0 - Internal Server Error
    An unknown FastCGI error occured Detailed Error Information
    Module FastCgiModule
    Notification ExecuteRequestHandler
    Handler PHP via FastCGI
    Error Code 0x8007010b
    Requested URL http://<IIS_HOST_NAME>:80/ucourse/integration.php?LOGONUSER=TestUser1001
    Physical Path C:\inetpub\wwwroot\srvr2\ucourse\integration.php
    Logon Method Anonymous
    Logon User Anonymous

    Seeing the Physical Path still pointing to a windows-based address leads me to think that the URL rewrite is filtering, but for some reason not rewriting.

    Thanks for your help! :-)

    You url rewrite rule is incorrect - the url match does not include the hostname, but only the url suffix beyond the current config location, so you match should look like ucourse/* and you should add a condition to have {HTTP_HOST} match the hostname you want - the freb log should have made clear that this rule was not being matched and the exact input used to match this rule.
