Hi  Yurong,

FRT didnt create any logs. i think rule itself is wrong. Can you please help me with the rule for rewriting the below scenario rule ?

Without reverse proxy URL is like this 

https://webapplicationidp-r1.xedge.com.sg/authuser.aspx?ref=https://webapplication-r1.xedge.com.sg/templates/idpconnect.w3p;fromUrl=http%253A%252F%252Fwebapplication-r1.xedge.com.sg%252Findex.w3p

Same with the below Rule "Reverse Proxy to Application"

    <rule name="Reverse Proxy to Application" enabled="true" stopProcessing="true">
    <match url="^(.*)" />
    <conditions>
    <add input="{HTTP_HOST}" pattern="webapplication-r1.xedge.com.sg" />
    <conditions>
    <action type="Rewrite" url="https://webapplication.xedge.com.sg/{R:1}" />
    <serverVariables>
    <set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
    <set name="HTTP_ACCEPT_ENCODING" value="" />
    </serverVariables>
    </rule>

rewrite it as 

https://webapplication.xedge.com.sg:444/authuser.aspx?ref=https://webapplication-r1.xedge.com.sg:444/templates/idpconnect.w3p;fromUrl=http%253A%252F%252Fwebapplication-r1.xedge.com.sg%253A444%252Findex.w3p

This is URL is not reachable. because authuser.aspx is hosted under "https://webapplicationidp-r1.xedge.com.sg:444" in the backend server. This same IDP url is having a reverse proxy rule in the proxy server as below.

    <rule name="Reverse Proxy to IDP" enabled="true" stopProcessing="true">
    <match url="^(.*)" />
    <conditions>
    <add input="{HTTP_HOST}" pattern="webapplicationidp.xedge.com.sg" />
    <conditions>
    <action type="Rewrite" url="https://webapplicationidp-r1.xedge.com.sg/{R:1}" />
    <serverVariables>
    <set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
    <set name="HTTP_ACCEPT_ENCODING" value="" />
    </serverVariables>
    </rule>

Could you please help to create a rule which will work for this scenarion ? We need to create a URL something like this below.

    https://webapplicationidp.xedge.com.sg:443/authuser.aspx?ref=https://webapplication.xedge.com.sg:444/templates/idpconnect.w3p;fromUrl=http%253A%252F%252Fwebapplication.xedge.com.sg%253A444%252Findex.w3p
