Irule: how to resolve DNS queries

Hi,     I have some doubts in the creation of an irule in a LTM.     I have a HTTP petition incoming in a LTM. I have to extract the url of the header, for example www.google.com...

Ok, thank you very much.

 

 

One more question. Do you think it is really a good idea to implement that proxy in a BIGIP LTM 3600??

 

 

I mean, the final iRule should be quite complex, and perhaps it will end in a high usage of CPU and a bad performance of the LTM.

 

 

Till now, all the iRules implemented are quite simple, and they do not affect very much the traffic, but this seems to be a complex one and I have no experience with these kind.

 

 

I have to say that the solution is for a mobile internet provider, so the number of petitions should be quite high. Actually, the virtual where will apply the iRule has 10 K concurrent connections.

 

 

Finally, one more thing. When loading a web page, there are a lot of objects downloaded with diferent GETs. I think each GET is a different petition and a new DNS resolution, do you know if it is ok??

 

 

Thank you very much!!
