get the HTTP command parameter in cfml

[albertkao]

How to get the HTTP command parameter in cfml?

e.g.

if the HTTP command is

GET /DATA/pg/index.cfm?lang=en HTTP/1.1

then the parameter should be

lang=en

if the HTTP command is

GET /DATA/pg/index.cfm?lang=fr HTTP/1.1

then the parameter should be

lang=fr

I think that cgi.query_string is what you're looking for.

I put
<cfdump var="#cgi#">
<cfdump var="#http#">
<cfdump var="#url#">
in index.cfm.

HTTP_REFERER returns
/DATA/pg/index.cfm?action=edit

QUERY_STRING returns
action=edit

I do not see "lang=en" anywhere.

Try creating a file named "cgitest.cfm" with the content:

<cfoutput>#cgi.query_string#</cfoutput>

Browse to http://localhost/cgitest.cfm?lang=en  (or substitute the appropriate path on your server).

The fact that HTTP_REFERER is populated makes me suspect that you have some redirection code, such as CFLOCATION, in your index.cfm file.

[albertkao]

Yes, there is <cflocation> in index.cfm.

Although I put cfdump before <cflocation>, cfdump still display QUERY_STRING as

"action=edit"

index.cfm is:

<cfdump var="#cgi#">

<cfdump var="#http#">

<cfdump var="#url#">

<cfif NOT IsDefined("action")>

<cfset action = "edit">

<cflocation url="index.cfm?action=#action#" addtoken="No">

<cfabort>

</cfif>

How to get the original parameter "lang=en"?

Do I still create the "cgitest.cfm" page?

My coldfusion version is 6.1.

Do one thing at a time.

Get rid of the cflocation until you know what is in your query string.  Once you have it sorted out, create the necessary session variable and use that on your next page.

[albertkao]

What is the session variable(s) look like?

Should it be stored in the index.cfm and/or the calling page?

[JR__Bob__Dobbs]

I'm not sure I understand your question. Can you provide some more specific information about what your are trying to accomplish?

You might start by reviewing the CF documentation on session variables.
