How to escape special characters from query string?

Try URL encoding the query string before sending downstream;-

when HTTP_REQUEST {
    HTTP::uri "[HTTP::path]?[URI::encode [URI::query [HTTP::uri]]]"
}

Thanks,

A small concern, since we are trying to encode the query string, and special character is being used within password parameter, do you think encoded string wouldn't be considered as an ACTUAL password?

Sorry, I don't understand code, it might look dumb to ask.

Cheers!

I am making an assumption (possibly incorrect) that the backend system that needs to use the password will perform URI::decode - it's worth a try.

What system is it that 'loses' the '' ? APM?

I've looked at your screenshot - do you even need the query string? Won't the system use the Authorization header if there is no query string?

I think no, the system refers the URI to extract the credentials out. I hope I understood the question correctly.

Sounds odd - not sure what the point of the Auth header is.

Are you sure the client system is even sending the in the query string? Perhaps it's a client error? If you are sure - where is the going missing? Is it there when the request hits the F5?

Hmm.... Honestly I am not sure what is being supplied by client, as the capture taken between F5 and backend server.

However the backend server should refer the auth header as you have mentioned, rather looking into HTTP query string. If that is the case, then the iRule would help resolving the issue.

I will share my latest observation very soon.

Thank you very much for your help. Darshan

take a tcpdump as the traffic arrives at the virtual server to see if is included.
