Response Header value Truncates after a particular length

[#1]

When I try to retrieve the response header (via java script or assign message)value it truncates at some length , for e.g my header is as below

When I retrieve the value to a variable it truncates , please look at expire towards the end

Why it is truncating? Is there any way i can retrieve the full value?

[ssvaidyanathan]

Hi @krishna.prasadm

Are you seeing this in trace ? How are you setting this value to a variable ?

[#3]

In the trace I can see full information :

I tried both java script and Assign message policy

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <AssignMessage async="false" continueOnError="false" enabled="true" name="extractHPPSession"> <DisplayName>extractHPPSession</DisplayName> <Properties/> <AssignVariable> <Name>HPPSession</Name> <Value/> <Ref>response.header.Set-Cookie</Ref> </AssignVariable> <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables> </AssignMessage>

So where is the value of the variable truncating? Is it when you see the value of the variable in the trace tool?

[#5]

no when i retrive the value to the variraible ..

[Former Community Member]

Ok, so my question is how do you know that value in the variable is truncated? Are you the checking the value of the variable somewhere in a condition or something? Maybe helpful if you can share your proxy bundle here.

[#7]

I have printed the value in the trace print command and stored that value as the accesstoken attribute, both the places it is truncating ..

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <AssignMessage async="false" continueOnError="false" enabled="true" name="extractHPPSession"> <DisplayName>extractHPPSession</DisplayName> <Properties/> <AssignVariable> <Name>HPPSession</Name> <Value/> <Ref>response.header.Set-Cookie</Ref> </AssignVariable> <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables> </AssignMessage>

i am using above assign message policy to retrieve the vlaue.

[#8]

attached is the proxy bundle, which simulate the issuerestrunc-rev1-2016-06-23.zip

Hi @krishna.prasadm just curious why the value of HPPSESSION seems to be different in the first section vs the other?

[#10]

that i took from two different calls, but same length for the two strings

[Former Community Member]

Where are you seeing the truncated value? In the trace window? Here is a thread on how you can write the output of the header variable.

[#12]

Trace is showing correct when I extract the value to the variable, then it is truncation. I am using assignmessage policy, even i tried java script also ..

[anilsr · Accepted solution]

@krishna.prasadm ,

It's by design, If any comma is present in the string Apigee treats it as a multi-valued header.

Instead of ,

response.header.HPSession

Use ,

response.header.HPSession.values

See more details regarding same here.

[#14]

hmmm .. values seems to be working . But the other one, APIgee is putting restriction over HTTP 😞

[anilsr]

@krishna.prasadm , Glad it worked. Can you please clarify what do you mean "Apigee is putting restriction over HTTP" ?
