I have tried with args & argM as specified in this link : http://wiki.alfresco.com/wiki/Web_Scripts_Examples#URL_Argument_Handling,

if i sent the request through the url - http://localhost:8080/alfresco/service/sample/args?a=2&b=3
i am getting the arguments as the output - a=2 b=3 a=2 b=3

respecitve code for arg, argM:
<webscript>
<shortname>Argument Handling Sample</shortname>
<description>Demonstrate access to single and multi-valued arguments</description>
<url>/sample/args</url>
<authentication>user</authentication>
</webscript>

// log each argument (assuming only one value has been provided for each)
for (arg in args)
{
logger.log(arg + "=" + args[arg]);
}
// log each argument (assuming one or more values have been provided for each)
for (arg in argsM)
{
for each (val in argsM[arg])
{
logger.log(arg + "=" + val);
}
}

<#list args?keys as arg>
${arg}=${args[arg]}
</#list>

<#list argsM?keys as arg>
<#list argsM[arg] as val>
${arg}=${val}
</#list>
</#list>

and for Header, I just replaced args with headers across all the places in 3 files,

please help me, if i am doing some thing wrong, Actually i am looking for Header Attribute value "UserAgent" value.

Thanks,

Hi Mike,

I have tried like this ${arg}=${args["useragent"]} & ${header}=${headers["useragent"]} to access the header attribute but i am getting an error saying,

06300112 Wrapped Exception (with status template): 06300111 Error during processing of the template 'Expression args["useragent"] is undefined on line 8, column 12 in org/alfresco/sample/args.get.html.ftl.'. Please contact your system administrator.

but i am not very sure whether i am doing it in the right way,

Thanks,
Saravanan.
