I know that it has a lot of data on it's query string, and that I should use POST when transferring large quantities of data. However, that's the way the system creates them... that was already done before I found the problem. The main problem is that a lot of modules have dependencies on this, and changing it would make it impossible to accomplish deadlines (next week).

Now we use that URL in the following iframe:

<iframe name="Contactos" width="100%" height="100%" align="middle" class="tabla_informacion" src="urlAbove" frameBorder="0">
</iframe>

However when the frame appears it just shows a blank screen, no callbacks at all are triggered on the server....

Now if we reduce the url length it works correctly. At first glance I thought it was a problem related to header lengths on jBOSS AS 6 (by default 8KB), so I changed it on the server.conf file and increased it to 64KB. No luck at all...

But then when I used Firefox's Poster plugin to create a GET request with the whole URL, it worked correctly and server breakpoints where triggered, meaning that it's not a server's problem, at least at the current URL length....

Maybe is a browser limitation? (We are using Internet Explorer...) is it a know problem? Or maybe there is something that I'm missing when calling iFrames?
