HTTP Profile :: Vary Header Help

I'm not too familiar with the Vary header and whether there is a good way to address this in the configuration. But if you want to remove everything including and after the first comma, you could use scan:

 

 

scan everything not a comma into precomma and the rest into ignore

 

scan [HTTP::header Vary] {%[^,]%s} precomma ignore

 

 

Update the Vary header value with the scan output

 

HTTP::header replace Vary $precomma

 

 

Else, getfield would allow you to do this without the intermediate variables:

 

 

Update the Vary header value with first field of the Vary header value, delimited by commas

 

HTTP::header replace Vary [getfield [HTTP::header Vary] "," 1]
