Converts any special characters to hex encoding

There is a command that can change string to hex

 

 

 

binary scan $string h* pkt_in_hex

 

log local0. "String in hex is: $pkt_in_hex"

 

 

But I need to convert only special characters of a string to hex encoding. Do you know how I could do it? Thanks

I am not sure where I follow? Do you need to convert them in general or do you need to convert them problematically in an iRule?

 

 

I have to make a irule where the value of a query parameter can contain some special character and it is necessary to convert these characters into hex.

 

Can you post and example of the full string with the querry. Also when it's converted where are you planning to use it?

I have to translate the following rewrite (apache) to irule:

 

 

RewriteMap escape int:escape

 

RewriteRule ^vegetables/(.*) vegetables.php?$1&HTTP_USER_AGENT=${escape:%{HTTP:User-Agent}}

 

 

The problem is that I don't know how translate the escape function.

 

I'd guess that's doing URL encoding--not base64 encoding. You could use [URI::encode [HTTP::header User-Agent]] to URL encode the User-Agent header value.

All of the references I could find online for the Apache mod_rewrite escape functionality indicates they use URL (aka percent) encoding. The regex there doesn't quite make sense though as it's only going to match a URI starting with vegetables. A relative URI must start with a forward slash and an absolute URI must start with the protocol.

 

 

As CB suggests, can you provide some sample requests and the rewritten result?
