REMOTE_ADDR Problem on WebFarm

[Mark Profile]

Hi there

i'm trying to get the clientIP on my frontservers
so i have to set REMOTE_ADDR to the value of HTTP_X_FORWARDED_FOR

now REMOTE_ADDR holds the ip of our LoadBalancer

is this possible?

please help

Hello,

Can you shed some light on your overall configuration?
Did you make loadbalancer using Helicon means? If so, it should work.
What rules do you have? What is the schema?

Load balancer: ARR/Microsoft UrlRewrite
front servers: Helicon isapi rewrite 3

we lift a big website (helicon rewrite) with thousands of rules to a webfarm
we need the clientIP on the front servers

so we need to know if its possible to overwrite server variables
otherwise i have to migrate all Rules to UrlRewrite, there this is possible

Code: Select all

        <rule name="IP" patternSyntax="Wildcard">
                    <match url="*" />
                    <conditions trackAllCaptures="true">
                        <add input="{REMOTE_ADDR}" pattern="xxx.xxx.xxx.xxx" ignoreCase="false" />
                    </conditions>
                    <serverVariables>
                        <set name="REMOTE_ADDR" value="{HTTP_X_FORWARDED_FOR}" />
                        <set name="REMOTE_HOST" value="{HTTP_X_FORWARDED_FOR}" />
                    </serverVariables>
                    <action type="Rewrite" url="{R:0}" />
                </rule>


but a hell of work
i rather would stay with your product

As far as I understood you want the rule provided to be transferred to ISAPI_Rewrite?
Unfortunately, ISAPI filters can't change server variables. HOwever, HeliconApe can. Is it IIS7?
