How to pass a large value to a parameter of a service

Question

Hi Everyone,
I need to execute service GET_SEARCH_RESULTS and want to provide values to its parameter QueryText. I am calling the service in the following manner:
http://localhost/idc/idcplg?IdcService=GET_SEARCH_RESULTS&QueryText=<$keyTagID$>&ftx=&AdvSearch=True&SortField=xAvgRating&ResultCount=5
hence passing <$keyTagID$> to QueryText. Now in my case, this variable <$keyTagID$> is becoming very large consequently making the whole of above URL very big. Its crossing the permissible limit of 2038 characters by Internet Explorer. Thus error 'URL too large' comes when I am executing the service.
Please suggest me how to execute the service 'GET_SEARCH_RESULTS', so that I can provide a large value to the parameter QueryText. I thought of making use IdocScript function 'executeService', but so far as I know this function accepts only one argument which is service name. Thus how to provide values to parameters of a service with 'executeService' function?
Thanks & Regards,

Hi,
To send large arguments over HTTP you have to post them, basically setting up a form similar to this:
<form action="<$HttpCgiPath$>" method="POST">
<input type="hidden" name="IdcService" value="GET_SEARCH_RESULTS"/>
<input type="hidden" name="QueryText" value="<$keyTagId$>"/>
<input type="hidden" name="ftx" value=""/>
<input type="hidden" name="AdvSearch" value="True"/>
<input type="hidden" name="SortField" value="xAvgRating"/>
<input type="hidden" name="ResultCount" value="5"/>
<input type="submit" name="submit" value="submit"/>
</form>
I'm not sure how much that helps if your users are currently just clicking a link. You could hide the form somewhere and have your link execute a javascript function which then posts the form.
