no http header in my request

hi all,

 

 

quite new to iRules, but already did my first steps (some of them successful). But now I am blocked. I have to make a normal http to https replacement, but I think I have a problem before.

 

 

I have my ltm configured to do ssl offloading and forward as http. unfortunatly the forwarded request only contains the GET line, nothing more.

 

 

 

GET /csc/

 

 

GET /csc/

 

 

 

 

HTTP/1.1 302 Moved Temporarily

302 Moved Temporarily

 

 

This document you requested has moved temporarily.

 

 

It's now at .

 

 

 

 

As there is only the "GET /csc" my Appserver can not reply with the correct http://.../csc

 

 

why is there only a GET?

 

 

Virtual server has stream profile enabled, but even with no stream profile and no iRule, I still get only "GET"

 

 

before doing something with iRules I think I should fix this, isn't it?

    I think its not an server issue. If I access the server via another interface than LB, I can see in the trace a complete HTTP request header:

     

     

    GET /csc HTTP/1.1

     

    Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*

     

    Accept-Language: en-US,de-at;q=0.5

    Accept-Encoding: gzip, deflate

     

    Host: 10.232.9.84:7103

     

    Connection: Keep-Alive

    with this, the server can answer with a 302 moved and send the correct url, Location header and href in the response

     

     

    but via LB the client requests get cut to only "GET /csc" and nothing more - therefore server can not send the correct redirect url...

     

     

    what I do not understand: why is the requst via LB truncated??

    ok, solved ;-)

     

     

    stupid thing, if you have a monitor doing just a /csc its normal that you see only the GET ;-) mixed it with real client requests

    Here is a good tip to avoid getting confused between real client requests and BIG-IP health monitor checks on the web server.
