iRule to persist on tcp_content

Hi unRuleY,

I was hoping you would reply, I like'd your work on the MSRDP problem.

Here's the thing, I have 3 different pools of Servers (3 services) I have client infor in the X-Client-IP header (you can refer to my original post,5:07AM) The rule I developed works fine on non persistent TCP as there is only going to be one request with one X-Client-IP in a TCP connection. However when enabling keep-alive and manipulating the appropriate offsets and carriage returns it does not fire.

Can I use Client data on its own without a client accepted event, how can I loop within the client accepted to retrieve all possible X-Client-IPs in a keep-alive TCP. Here's my hack at it:

   
 when CLIENT_ACCEPTED {  
    TCP::collect   
 }  
 when CLIENT_DATA {  
     For requests arriving using a Content-Length header  
    if { [TCP::payload contains "Content-Length:"] } { 
       set ConLen [TCP::payload value "Content-Length:"] 
       set hashKey [findstr [TCP::payload] "X-Client-IP" 13 "\r"] 
       if {$hashKey ne ""} { 
          persist uie $hashKey 1200 
       } else { [TCP::payload contains "Encapsulated: req-hdr="] } { 
          set hdrStart [TCP::payload value "Encapsulated: req-hdr="] 
          set hashKey1 [findstr [TCP::payload] "X-Client-IP" 13 "\r"] 
          if {$hashKey1 ne ""} { 
             persist uie $hashKey1 1200 
          } 
       } elseif { [TCP::payload contains "Encapsulated: req-hdr=0, null-body="] } { 
          set hdrOSet [TCP::payload value "Encapsulated: req-hdr=0, null-body="] 
          set hashKey2 [findstr [TCP::payload] "X-Client-IP" 13 "\r"]  
          if {$hashKey2 ne ""} {  
             persist uie $hashKey2 1200 
          } 
       } 
    } 
    TCP::release 
 } 
 

As you can see it gets a little complicated with the offsets, so I just want to precise exactly the offset values:

Encapsulated: req-hdr=0, req-body=412

The request header starts at 0 and the body at 412 bytes.

Encapsulated: req-hdr=0, null-body=412

The request header is 412 bytes, there is no request body.

The BIP is 9.0.4 I would also appreciate a little help on the server response problem.

Cheers,

Vinny.
